Nestled below the foothills of San Dimas sits Kosmos Burgers, the kind of place you don’t find so much as run into. Blink while driving and you’ll miss it. And that would be your mistake. It looks like it used to be something else once. Maybe an old McDonald’s. Maybe just another forgotten fast-food joint that time left behind. Kosmos didn’t bother erasing that history. It embraced it. Red vinyl booths line the room like they’ve absorbed decades of conversations. The napkin dispensers are the old metal kind, heavy and honest, the kind that don’t apologize for existing. I opt for the bacon cheeseburger. It takes a while, and that’s the point. It’s made to order, like the fries, not rushed and not pretending otherwise. The patty is thin and char-broiled, with a familiar taste you don’t question because you already trust it. The Thousand Island brings it all home. There’s comfort in that kind of burger. You know exactly what you’re getting, and it’s exactly what you expect. It’s like all the small mom-and-pop joints learned the recipe from the same quiet place long ago. Most of those places are gone now. This one isn’t. The drinks come in a “small” that’s really a medium, and go all the way up to a large that’s massive. The kind that keeps you hydrated for the long drive ahead, wherever you’re headed next. The place sits on old Route 66, and it knows it. There’s no manufactured nostalgia here. Just the real thing. A roadside stop that reminds you how travel used to feel before everything became optimized, branded, and disposable. Be sure to grab an ice cream. Yes, their machine is actually in service. I make a point to stop here whenever I’m passing through Azusa, Glendora, or San Dimas. Not because I have to. Because it feels wrong not to.

This is our "go to" restaurant. I'm almost afraid to review it because it will become so popular that it will get crowded and loose its quality. Great breakfast deals and menu that will surprise you. Small booths and parking is so/so. They do have a drive-thru that seems quite busy. Everything from burgers to greek salads.

I have been going to this place for over 20 years and it has always been pretty good. But I went this morning for a breakfast burrito and was very surprised. They have their own homemade red salsa. I have to say it was really good. I think I will go back to buy some of their salsa. Their breakfast burritos are filled with bacon, egg, and potato at a good price

Excellent burgers, and a complete menu of Mexican and Greek specialities. BREAKFAST SERVED ALL DAY. Large and hearty breakfast burritos. Very friendly staff!

I had a drive-through experience par excellence this morning. I ordered an Ortega and egg burrito adding bacon. When they asked me if I wanted sauce, I said yes hot sauce, please. One bite of the burrito I knew that I had found an excellent restaurant. The hashbrowns inside the burrito were crispy. The seasoning was perfect. The Ortega added a burst of flavor that I didn’t expect even though I love Ortega canned peppers. Then I tried the salsa that they gave me. It wasn’t a hot sauce. It was their salsa and it was the bomb. I could not have been happier to be eating that burrito at that moment.

I ordered pastrami sandwiches and fries. When I tell you, babyyy, it was scrumptious. Going to get another one this week and the customer service was impeccable. Love it!

An all around SOLID American (multi-cuisine) restaurant. This is my first time, but not my brother-in-law’s first time here. He enjoys the lunchtime burgers, but today we were there for breakfast. I usually establish my review opinions by ordering a breakfast burrito. My eye was caught by the ‘all meat’ breakfast burrito. You will notice that it had sausage, ham, and bacon with the usual hashbrowns and eggs. It was enormous, as described on the menu. My brother-in-law got the pancakes and eggs with sausage. The pico de gallo and salsa were spot on and made the breakfast burrito a hit compared to what I usually find in the area. I’m not a small guy and I can eat a pretty decent amount. I had to bring half of my burrito home. I also like that I could self serve my 3 cups of coffee. They had vanilla creamer, and the coffee did not have that typical bitter, weak, diner taste. I’m sold on their breakfasts. Soon, I will return to give lunch a go-around. Photos with iPhone 13. Update: Avocado burger and onion rings. 👍

I love this non-chain hamburger joint as do my kids! The menu is quite expansive and versatile, offering many options for breakfast through dinner. My family and I enjoy their chili fries and lettuce wrapped burgers. Enjoy.

Tasty wagyu smash burger close to the beach and in the parking lot of a juice shop.

I could easily post these pics and just write nothing, and the pics would speak for themselves. However, there is so much to say here. When I first opened it up, all I could do was laugh. You could cut it lengthwise and have two, good sized burritos. It could easily feed a family of four. It is the "All Meats Giant Burrito" and is the biggest breakfast burrito around. I bought it two days ago and as of day three I still am trying to finish it.
