Food was good but the portions were super small.. it seems that since we used the Groupon, they cut the portion down to hardly anything.

the sushi here is so good. i have not had it in almost two years due to covid, and was so excited to have it. the one downer was we came in and were told we needed a reservation...only one other couple in the restaurant and they left while we were looking at the menu. we have been there many times, and never were asked if we made a reservation. so we ended up making a reservation, having tea while we waited in the booth, starving, and finally eating more than an hour later which is the soonest the manager said they could make the reservation for. the waiter was super helpful and kind and seemed very embarassed and apologetic. good management bends rules when they see that there is no logic in having a reservation when there are no people eating, and the one set of customers you have almost left because you insisted on the reservation rule despite not other customers (one or two came later) especially when they are returning customers. and yet, i will return, because their sushi is marvelous. but it made me sad to be treated like that when there was no logic to be had. none.

About Koisan

The chefs at Koisan take no shortcuts in creating traditional Japanese food. Just minutes from Disneyland, diners can enjoy an extensive menu of Japanese staples, from udon soup to chicken sukiyaki. There's even a daily bento box, which features a constantly changing selection of the chef's specials. But the real star of the show is the sushi selection that's split up into three sections: fresh, tempura, and baked. Read on to learn more about Koisan's rolls:

  • Fresh: The Lemon Ultimate Philadelphia features a filling of asparagus, avocado, cucumber, and cream cheese, and is topped with salmon and lemon.
  • Tempura: The Final Four includes spicy tuna, spicy crab, spicy scallops, and a spicy crunch on the inside with tuna, salmon, yellowtail, albacore, and shrimp tempura on the outside.
  • Baked: The Motoyaki roll is stuffed with crabmeat, avocado, and cucumber before it's topped with baked scallops, pink shrimp, crabmeat, mushrooms, onions, and masago.
