I ordered the beef sukiyaki and two sushi rolls. Sushi was great! I got spicy salmon and spicy scallop because the hostess suggested I get it. The side salad was great! Amazing dressing and so refreshing along with the miso soup. My main course is always my go to when I come here. The sukiyaki is so flavorful and fresh. Definitely would recommend this place

I never have to wait to eat here. Food is delicious, fresh and great portions. Always am joyfully greeted by employees, especially the sushi chefs. There has never been a rushed feeling like some places can be, staff was attentive but let us have our time like a normal restaurant can be. Love it. Happy hour prices are great, can fill up on plenty of items. Love going here, I just need kids to like it too, too picky!

My experience at this sushi restaurant was terrific. Parking was easy. Staff was friendly and welcoming. I was served plum paste and fresh wasabi with my order of salmon sashimi. The Orange City Roll was delicious. The garlic edamame was very good as well.

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.

Nikki Patterson (Avengling)
Food and staff was amazing. The sauces complemented the flavor of the fish instead of covering them up like a lot of the trendy sushi restaurants we’ve been to recently. They had some live fish on the menu that came out beautifully presented and fresh. Service was polite and attentive. We got there very close to closing without realizing it and the staff was still polite even though they were probably tired and ready to go home for the day.

Fresh and delicious with so many daily fish specials. This restuarant has remained in business for 36 years for a reason. Service was very good.

Gary Bradford
When we arrived there were 7 empty seats at the sushi bar and no one waiting in front of us but the wait to sit there was 15 minutes. Don’t understand why and the draft beer was warm and flat. This place has some serious issues. Redeeming qualities: the sushi portions are big and the fish is fresh. Still don’t think I’ll be back.
