It’s a great looking restaurant with friendly people and exceptional food at a very reasonable price. I had a great time and haven’t been hungry since and that was 7 hours ago. Recommend the katsu bento. Two Michelin stars, minimum ⭐️⭐️

The movement has been there for over 20 years! Never disappointed with their food. My only complaint is the small dining table and the long wait. 90% of the time, I visit them for the sashimi special! Please be aware that this is a more traditional Japanese restaurant. They they don't have much of those curly pastries. But expect authentic, very fresh sushi!!!

My family and I have been coming to Koisan for over 5 years. Food is delicious but service has always been bad. Every time we came to eat, the restaurant wasn’t busy and we had to wait a long time for our food to be served. Servers often messed up our order, and we had to wait a long time just for an appetizer as simple as edamame to be served. I’m so disappointed and unfortunately we will not be coming here anymore. To the management: your chefs are amazing but service terrible. You have to be more selective when hiring servers because they are representing your restaurant.

The rolls where kinda falling apart. Green tea was fine. At least the cup was super cute. Everything was tasty though. The brine for the pickled veggies is a bit in the stronger side. The host was super friendly and the staff is nice. Good amount of seating and clean. For two people we spent I think about 60 maybe a bit more.

Karen, I am a customer. My advice to you is to visit the restaurant, and ask its owner.
