Okan Diner: Experience Authentic Japanese Noodles and Bento Boxes

Shin single-handedly saved an entire orphanage, carried an Olympic torch from saving a world leader, received the Nobel Peace prize, all before being the best server here. 11/10 thank you for handling our party of 12.

Super cozy, laidback restaurant, with lots of great Japanese comfort food. The menu is pretty diverse so you can find some dishes here that aren't as common to see, and there's a good drink selection too. We really enjoyed our dinner.

I owe Shin, our waiter for tonight, a life debt for the best service I’ve ever had at a restaurant in my life. He single handedly grew our crops, raised our children, did our homework, made us laugh, and got us our food in record time still steaming. He wins a gold record in serving and if he has a boss who is reading this, he deserves a raise and also maybe a smooch on the cheek. The food was stunning and the prices were great, amazing, will come here again (mostly for Shin)

Great food, service and experience. Very authentic Japanese food. We went right before 7 on a Thursday and it wasn’t terribly busy. We were able to get seated quickly. Their appetizer menu is huge and we ordered the beef tongue, the fried nankotsu (chicken cartilage), and the pan fried onigiri (rice ball) with miso, which were all fantastic. For our main courses, my wife ordered the fried kaki (oyster) and I had the chicken nanban, a fried chicken with a tartar sauce style topping. Everything was fantastic that we tried and I wanted to try more. Next time we’re in San Diego we will definitely be back.

A friend recommended this, we came in, took a while to order from a very interesting and diverse menu. We ordered udon, shishito peppers, the spicy tuna roll and the house sake. Everything was delicious.

Highly recommend the udon. First bite it made me feel like it’s Mac and cheese and the more I ate, I felt like it’s Alfredo. Super creamy and unique. The salmon roll is very fresh. And the chicken in the curry is super crispy. We finished the three dishes with two adults!

When I stepped in they were playing Japanese music from the past few years so huge nostalgia factor to start. Their menu was authentic and the atmosphere definitely fit the bill. The servers were kind and asked if I needed anything or needed to order more food. I thoroughly enjoyed the yakitori, udon, and unagi rice biwl I ordered. Would definitely recommend and plan on eating here again.

Okan Diner in San Diego offers a welcoming spot for Japanese comfort food, especially if you're craving curry. The curry I had was hearty and flavorful, with tender chunks of meat, potatoes, and carrots in a rich, mildly spiced sauce served over sticky rice—perfect for a satisfying meal without being too heavy. The dining area feels casual and cozy, with friendly staff who explain the menu highlights quickly and keep things moving during busy hours. It's a great neighborhood vibe, ideal for solo diners or small groups looking for authentic home-style eats. The curry stood out for its balanced taste, not overly sweet or greasy like some versions, and came with a side of pickled veggies for a fresh contrast.Portions are generous, and simple sides like miso soup added to the comforting experience. Situated conveniently in the heart of San Diego, it's easy to access and offers solid value with meals that leave you full and happy. While the space is straightforward without fancy frills, the quality of the curry and efficient service make it worth a return visit.
