Opinions de J SAN RAMEN Fullerton
Gen Korean BBQ in Fullerton is a MUST-VISIT spot! 🤩 We had an AMAZING experience and can't wait to come back! The food was top-notch (loved the spicy pork belly!), but it was the service that really STEAL THE SHOW! Johnny, one of the managers, was INCREIBLE - super friendly, knowledgeable, and made us feel like part of the family! He shared some awesome stories about Gen and was happy to chat with us. We tried their new drinks and WOW - the Lychee Oolong tea was a GAME CHANGER and the Strawberry Milk was TO DIE FOR 🍵. Huge shoutout to Johnny for making our dinner so special! 5 stars isn't enough - I'd give it 10 stars if I could. Can't wait to be back!
Had a delicious Korean buffet BBQ here yesterday evening around 6pm. It was quite busy, and we waited about 15 minutes for a table for four. The meat was really top quality, and if you're a meat lover, I definitely recommend this place!
We went today and we were treated so well by most of the staff we had a very nice server and the manager jonny was so sweet and on top of his game we had issues with our grill and he popped in and saved the day we didnt want to lose our table since it was in a good private area which we loved and he fixed the issue and we were able to enjoy our dinner in peace. You have to try the new boba drinks they are actually really good quality and delicious must try! 😋 The only bad thing I do wanna say is that the other manager I didnt catch his name but he might of been Latin tall and husky was kinda rude and really put a damper on our day he said he was going to charge us $5 extra each for not finishing our food we weren't even done eating yet... that really caught us off I've been here so many times and never had anyone say or do that to us... His delivery and tone was very rude and inappropriate. We were all smiles having a great time and he just popped in with his negative presence and attitude to dampen our mood.... still wont let it ruin my experience since everything else was above standards.

Went in for a Father's Day lunch with my significant other. First time here. Jose Roacha was our server. He explained the menu and how to order. We ended up with Hawaiin, Bulgogi and Kalbi rib. The salad was so tasty. I probably ate the whole bowl. And shared little with my boyfriend. Jose was very attentive and checked in on us, made us laugh. I really wanted him to sit down and join us. He refilled our drinks. Yes this is his job, but he made us feel as if we were his only customer. However I seen he gave those guest the same service. My tip reflected his service!
Israel our server greeted us with amazing service, never had us waiting, he was fast and friendly and he even served us our drinks before his shift ended making sure we get our refills in which we all appreciated very much please have him be shift leader because he literally had the floor at ease and on time with our meats and sides . Thank you Israel 💙
Gen KBBQ in Fullerton is amazing! It was a busy night, with a crowd waiting outside for their turn to dine in. My date and I waited about 15 minutes and had great customer service during our dinner. Our server was very friendly and attentive. The staff changed our grills several times without us asking. I loved the quality of the meats, rice paper, and how they had Carne Asada Steak with Tortillas. The vibes and physical location of this restaurant were amazing. Absolutely love this location!
The manager Johnny really took care of us. Came to our table to check in on us, had a great conversation with us and offered our table a sample of off menu drinks. Awesome atmosphere and great service will definetly be back.
We tried this place for the first time last night for a celebration dinner and the food was very good. Wait lines were a little too long but the environment was something we enjoyed as family. Would come back here

We had a great time at Gen Korean BBQ! My kids really enjoyed the experience — it’s something different and fun for the whole family. For someone who likes to take care of their own BBQ, this place is amazing. The food was fresh, the atmosphere was lively, and the overall experience was fantastic. Highly recommend!
Over all its pretty good. Nothing crazy but still offer good variety. Must tries would be the prime steak, short ribs, and mango twist things for dessert.
The food was good. The portions were a bit small. I think they do this on purpose so people don't waste food. It was my first time coming to this location so it was nice. To get different cuts of varieties. He had to pay a bit extra. It was nothing excessive. It was fair.
Came on New Year’s Day 2026 and we waited 30 min to be seated. Apparently several servers called off so we initially were being served by the manager. He took our drink orders and after bringing our drinks we didn’t see him again. After waiting for 15 min we were then handed off to Zay, our server. Under the circumstances he was very good. I have no complaints for Zay. I just wish the communication between the manager and him was better. As far as food, it was average at best. I do not like how dark it is in the restaurant. Also the vent system could be better. Too much smoke inside. The floors definitely were slippery due to the floating grease in the air. We came cause we had a gift card. I doubt we’ll be coming back.
We came on a weekday right after it opened. The menu can be viewed on the phone but you have to order thru the waiter. It wasn't that busy but the waiter didn't replace our grill on time so our food was always burnt. The quality of meat was just so so and the waiter lost track of our orders ended up bringing a lot of food in the end. I would suggest to let people order it thru the phone so that it is convenient to track what they have ordered.
We visited many different GEN branches in California and Texas. This branch did not meet my Food, service, and atmosphere expectations. The food portions were too small, so I had to order many times for four people, which was bad because they do not have enough staff to keep up with demand. The restaurant inside the room was too hot, keeping me sweating while eating! GEN has been my favorite restaurant, but I think this restaurant's branch could be better. I would recommend GEN but not this branch.

Understaffed for sure.Had a bad experience the last time we went as well, but decided to give it another try. We had to ask multiple times for our first round of meat. They were out of rice paper and forks !!! Waitress we had was not attentive and rude. My son and daughter in law had never been so they were unsure how to order. So when ordering sides/appetizers the waitress asked “are you gonna eat it?” Like what!! On top of it all it was my daughter’s bday. Not an overall good experience at all. Love Gen , but we won’t be back to this specific location for sure .
If anyone else liked the salad from here you'll be disappointed to know they changed the recipe. Idk why they thought they had to reinvent the salad but what they have now is a warm cabbage dish. Food and service is still good. Please bring back the salad! If it wasn't broken before, don't fix it now when no one asked.
Came to GEN KBBQ on New Year’s Eve since Mr. BBQ was busy. This visit reminded me why I stopped coming here. The chadol brisket was very dry and tasted like shredded beef, and they don’t offer all the sides unless you ask. While the beef belly was decent, the overall meat quality, cleanliness, service, and atmosphere don’t compare to Mr. BBQ in Fullerton. Hopefully management reads these bad reviews and turn things around.

Come here as a single or couple is fine, as a big group is worse. 4 meat dishes per order, each dish is 1 piece of meat. Party of five needs to wait for the second round of order. Each portion is so small and the wait is long to get to the next round and they asked for the time when we sit down since there is 2 hours limit. Basically, All you can eat against the two hours marks and the turn around order. Never come here again Adding, the grill power is only good for 2 to 3 person party. Here is the photo of 10 or more minutes waiting between order round. Updated, after another 15 minutes waiting, nothing happened. Just ordered a Rice paper and cucumber pickle. And continued to wait.
I stopped by this location because I didn’t want to drive to Cerritos, but what a disappointment. As shown in the attached picture, I was served a frozen, tiny slice of brisket that was stuck together. During the busy lunch hour around noon, there was only one server trying to handle everything — which clearly affected the quality of service and food.

Bad service today, got ignored Tessa R. Was our server. Disappointed to say she only came up to us once and after the first round we decided to leave because the grill was burned our drinks were out and still hungry at it.
This is easily the worst kbbq restaurant i have ever been to. Easily. Very very poor quality meat. All mushy. Beef brisket is like leftover meat trimmings and scrap meat. Very small portions + beef brisket that shrink and shrink and shrink as they get cooked. Not enough for even a party of 3 guys (limit 4 meats each order so you have to keep ordering - for which i deeply appreciate our server). On top of that, no ventilation above each table like other kbbq restaurants have. Uncomfortable air quality. Service was good. Very diligent server. But long wait time in the beginning when we sat down - over 10 minutes til we got greeted by a server; and over 25min total when the first plate of meat was put on our table. Why gen quality went downhill so much?? So absolutely disappointing. Extreme disappointment. You will understand if you still decide to visit here.
Right off the bat, need to state that our waiter, Israel, committed credit card fraud on my card. If you get him, save your receipt because he will add his own tip on top of what you’ve signed for. Management seems to be in on it and tried covering for Israel until I threatened to get my bank involved. Still waiting on my refund, but have the proof needed to escalate this, hopefully that’s not needed. Even before being literally scammed, I thought it was bizarre that the server told us he would not be able to split the bill more than 2 ways. This does not make any sense to me, that in the year 2026, we cannot split a bill, especially when the pricing is per person. It just doesn’t help the fact that this location has workers that are looking to scam you. Food was good, would be hard to mess up serving acceptable meat. Atmosphere was bizarre, complete silence in there, no music. If you’re going here, just be careful + attentive to your receipt.
Horrible. Horrible. Horrible Went for lunch about a week ago with my family at 11:30am. Right off the bat the waiter was rude and didn’t take our order, no sides or sauces were out ready to go. Typical when you go to kbbq the sauces and sides are ready, for some reason the table are always never ready. Then we order and the waiter said we are out of mashed potatoes and rice paper. This has been the 3rd time we go there and this a happened. Don’t have items but expected to pay full price. Lost my business, will never go there again. Do better management
The experience was so chaotic. The staff were running around the entire restaurant, i do understand it was busy, but they all looked so lost and kept bumping into eachother. The meats werent that good and the bulgogi tasked old. The trays they bring the food on are all so dirty. The floors were extremely slippery, you have to talk really slow and they have wet floor signs all over the floor. It looks like they are having plumbing issues or something. It felt like such a dirty environment.
I’m really disappointed with our recent visit to Gen Korean BBQ. The quality of service has seriously dropped. Our server, Julian, was incredibly forgetful throughout the entire meal. Every time we asked for something, he would say yes, but then never follow through. We had to repeatedly remind him about basic requests, which made the experience frustrating and exhausting instead of enjoyable. He also never once checked in on our table to see if we needed anything. To make things worse, the host at the front didn’t acknowledge us when we arrived. No greeting, no eye contact, nothing. It set the tone for the rest of the night. About an hour and a half after we left, my partner started feeling sick and later experienced what appears to be food poisoning. That alone is enough to make sure we never return. This place used to be fun and reliable, but the decline in both service and overall quality is very noticeable. We won’t be coming back.
My party of four came in, we got seated right away the hostess was very polite. But our server Vanessa, short, glasses, black hair, had an attitude right away. It was our first time coming to a Korean bbq so we didn’t know how to order efficiently. So she was giving us attitude not helping what so ever looking at us like we’re dumb. Food was amazing though! She didn’t kill our night. First time ever having to give someone a zero tip. 😓
Took my wife and kid after work looking for an enjoyable meal tried this new place out, got seated at a table pretty fast, but our servers took way too long to serve us even though there was hardly anyone in the place. Left after the first round still got charged full price. Would recommend going to Mr. BBQ for a way better experience

ABSOLUTELY FILTHY I have never walked out on a restaurant before. This was such a horrible experience. I understand that in a Korean bbq restaurant, it gets a little greasy with all the mean cooking. When I tell you I had a PUDDLE OF GREASE at my feet. I almost fell multiple times walking through the restaurant. When we were seated, the booths were extremely cramped. My knees were hitting the table and I couldn’t sit comfortably. We ordered the dinner option. EVERY PLATE WAS DIRTY when we got our plates of food. A thick layer of old food and grease coated the plates our food came out on. On top of that, none of the food we got was correct. When we asked the waiter about it, he said they were busy and were just cleaning the dishes fast. There was maybe 30 people in the restaurant. I’ve seen busy and Gen and that was not busy in there. You are not too busy to provide a clean and healthy atmosphere. We asked for management and all she did was take the food back and avoid us. She didn’t apologize or have anything to say. We saw there was a second manager and we told her we were leaving and this was disgusting. She comped our meal that we didn’t even eat. It was such an inconvenience. The least they could have done was offer a coupon or something but when asked, she just walked away from us. This place is a health risk to anyone who may be allergic to food and is a hazard for anyone who sets foot in there. We drove 30 minutes to their Santa Ana location and had an amazing experience. Floors were clean, great music, awesome people, AND CLEAN PLATES! I’m a huge fan of Gen Korean bbq and I will 100% be going back, But I will NEVER go back to this Anaheim location. DO BETTER!!!
