Kosan Asian Fusion

Nice place to for lunch or dinner. I might even say this the nicest sushi restaurant in Sheepshead bay area) Service was good. We ordered Rock shrimp, Dynasty roll, and Crazy dancing roll. Shrimps were more like prawns(huge) could have been a little spicier) rolls were good. But the was not hot enough. Specially, when it is 40 degrees outside, would be good to get a good hot tea..

While going in the first though that comes to mind is sushi, but this should not be the case. The name says it's all, and the key word is fusion. You can find dishes from various Asian cuisines under one roof and they are the reason why I would give them 5 stars. The sushi are actually not as great as some places around, but who needs sushi when they have many amazing dishes. Their seafood udon is just perfect and considering that there is places in the neighborhood that serves it this will be my go to place from now on.

Thanks for the hospitality. we chose that place to have a snack and drink the famous Japanese beer asahi. we asked the manager if they have a happy hour, they don’t , but we were for first time, and manager kindly offered a discount on drinks. we tried tom yum soup and yellowtail sashimi, we really liked it. We will definitely come back again. I recommend it to all beer lovers, it’s fresh and very good taste. Food is also so good.

This Japanese restaurant is a gem! The warm, cozy ambiance, coupled with incredibly friendly staff, makes every visit delightful. My favorites include the mouthwatering sizzling beef teriyaki and the irresistible ramen noodles.

Very very glad this spot opened up! Beautiful space and all of the food is has beautiful presentation! We sat in their back room and it was very cozy and secluded. Enjoyed the Odessa roll, Crazy Dragon roll & Bvlgari roll — all deeeelicious! Their tempura green tea ice cream is 1000% my fave in our area! Also definitely get the green tea to sip on throughout the meal! BTW The server was very sweet & helpful with choosing dishes. The only thing I didn’t love is we were brought out miso soup that we didn’t order (but enjoyed thoroughly…just thought they brought it since the restaurant was empty) and it was on the bill. For $2.50 though no biggie.

This is a relatively new place and my favorite sushi restaurant around. The BEST design snd ambiance among all other sushi restaurants here. Lovely for parties and eating alone. Besides I come here for a crab avocado soup, it’s amazing!

Sooooo Tasty, warm atmosphere and fast service. Jessie is very sweet and always recommends us the best special rolls with the freshest fish. Highly recommended 😍

A true gem in Sheepshead Bay! Kosan consistently delivers incredibly fresh, delicious sushi every single time. The quality of the fish is outstanding, and you can really taste the care in every bite. Jessy and the entire crew go above and beyond to accommodate us. They always make us feel welcomed—not just like customers, but like family. That kind of hospitality is rare and so appreciated. There’s only one sushi spot in Brooklyn for us, and that’s Kosan. Thank you for always taking such great care of us!

I brought 30 teenagers here for lunch after a college tour. The staff were welcoming, warm, and inviting. They were also very patient and kind and made everyone feel very comfortable. All of the students enjoyed their food tremendously! They all had various lunch specials (chicken/shrimp/veg teriyaki, chicken/steak hibachi, bento boxes, and more) which were reasonably priced, came with rice and soup or salad, and were sizeable portions. I will definitely return whenever we are in the neighborhood again! Thanks to the amazing staff for a lovely end to our trip!

We’ve been coming to Kosan Asian Fusion regularly as a family for dinner, and it’s hands down our favorite sushi place in Brooklyn! The sushi here is always fresh, beautifully presented, and full of flavor — every roll we try seems even better than the last.  What we love most is the welcoming and relaxed atmosphere — it’s perfect for family dinners. The staff are friendly and attentive, making everyone feel comfortable whether we’re ordering sushi, sashimi, or trying other dishes from their Asian fusion menu.  The menu has something for everyone in the family, from classic rolls to creative favorites, and even other Asian-inspired dishes that are delicious. The portions are generous, and the quality is consistently high.  Highly recommend Kosan Asian Fusion for anyone looking for a reliable, tasty, and family-friendly place to enjoy great sushi together!

My favorite sushi in Brooklyn. I have been going here since they open and it's still my favorite sushi restaurant. The sushi is super fresh and tasty. I tried almost all sushi spots in the area and Kosan has the best sushi. Place is super cute and love their private rooms for special occasions. Jessie the owner is amazing person, very friendly and honest.

Jessy, the owner, always makes sure her guests are happy. She is the best host and Kosan became our favourite spot for sushi. The food is fresh and tasty and staff members are very friendly. Highly recommend Kosan!

I’ve been to many sushi places around my neighborhood, but I’ve got to say that this is the best place. The food is always amazing and taste good, the service is great and the waiters are always fast and kind, and the atmosphere is welcoming, cozy, and clean. It’s a great spot to go to with friends, family, or even by yourself. When I deliver from this place, it always comes fast. Overall this is a great spot and I recommend it to everyone!

My server provided quality attention despite reports. The service quality alone validates this establishment. This restaurant offers affordable quality. The quality is top-notch! Visit this spot without hesitation!

Restaurant looks nice and clean, atmosphere is welcoming. The service was decent since we were the only customers there at lunch on a Wednesday at noon. The sushi tasted fresh and good. Will try again and order some other dishes for a broader review . update 5/9 ordered delivery and unfortunately both orders were incorrect and not good. So sad that the food isn’t consistent.

The restaurant is located in the Sheepshead Bay section of Brooklyn. They serve primarily Japanese cuisine. I ordered the sushi/sashimi bento box. The sushi/sashimi was fresh and tasted very good. It included a generous amount of mixed shrimp/vegetable tempura. The nabeyaki soup included upon noodles, seafood, mixed vegetables and an egg. The spider roll was prepared with deep fried soft shell crab, spring mix, cucumber, mayonnaise and caviar. The restaurant was very busy. Nice interior and long sushi bar.

Saturday evening drop by. This space is on my list for a while and didn’t disappoint a bit. This restaurant has open view so one can see throughout. They have special seating for group of 6 to 8 for private, secluded dinner with your guests. The space itself is nice and clean yet simple. The service is fast, prompt and more importantly attentive. The food I ordered was two rolls (California and spicy tuna roll) both equally delicious and tasted fresh. Also ordered entree Japanese rice that came with salad. All in all great experience, nice open space, excellent service, delicious fusion food.

Small. Cozy. Great menu! Christina was our waitress. She was so sweet and knowledgeable. Sushi waa awesome so was the beef ramen!! They have the best charred edamame!

My boyfriend wanted to try something new. I personally didn't like the food though. The soup wasn't good. I order seafood and the portion was small. They were closing in an hour so we had to rush to get our orders in before the kitchen close. He did say that his pineapple chicken he received alot of chicken. My drink which had mango was horrible. It tasted more orange juice than mango. I gave it to him. Then they didn't even have mango to put on the glass. The price I must say was decent. We sat near the window and it was cold. It felt like there was no heat.

For everybody that knows me in the Sheepshead Bay area, please do yourselves a favor and don’t go to this place. I would never go out of my way to write a bad review for anyone. I understand how important small businesses are to our community, and I genuinely try to support local establishments whenever I can. However, I am extremely frustrated and disappointed right now. I made a reservation for 16 people and personally called two days prior to confirm, letting them know that two additional guests would be attending. Everything was confirmed. Then, on the day of the reservation, because I didn’t pick up my phone, they decided to cancel my reservation and give the table to someone else. For a party of that size, that is completely unacceptable and incredibly unprofessional. We had coordinated 16 people around this dinner — schedules, transportation, everything — only to be told the reservation was canceled. No accountability, no real solution offered. What makes it worse is that after reading other reviews, it seems like this has happened to multiple people before. Canceling confirmed reservations to maximize tables is not how you treat customers, especially in a neighborhood where word travels fast. Do yourself a favor — do not book any parties here and do not rely on their reservations. If you’re planning something important, go somewhere that values its customers and honors their commitments. Very disappointed.

I was part of a group of 16 with a confirmed reservation, and this place completely dropped the ball. The reservation had been confirmed in advance, yet on the day of the dinner they canceled it and gave the table to someone else because the person who booked missed a phone call. For a party this size, that level of unprofessionalism is unacceptable. Coordinating a large group takes time and effort, and everyone showed up expecting a confirmed reservation; only to be told it no longer existed. No accountability, no apology worth mentioning, and no attempt to make things right. After reading other reviews, it’s clear this has happened to other people. Canceling confirmed reservations to maximize tables seems to be a pattern here. If you’re planning a group dinner or anything important, don’t rely on this place. Choose somewhere that respects its customers and honors confirmed reservations.

quite literally zero stars, very rude employees employees judging us based on our age, me and my friends went out to I go get lunch for my friends birthday party (we're 14) they forced us to pay a water charge because 2 people weren't eating?? absurd. employees are giving dirty looks while walking past us, and I found a FINGER NAIL in my food. I promise you skip over this location and go to tenda instead.

The place was almost empty and I waited for 1.5 hours for my food. Noone cared to ask or show any hospitality. Food is good but the was is ridiculous. Slowest sushi place ever. There are so many options on the block that serve way faster than this location. Highly disappointed. Especially because it was a weekday.
