I held a surprise birthday party here for my friend. It was easy to plan, just printed out their menu from their website took down orders, and came in early to give it to the cook. An assortment of food was ordered that day, everyone said theirs was delicious, even some first timers of Japanese cuisine. I would only suggest tasting the sauce for the salad before dumping it on there. It had a bold taste, but I've learned to like it now.
The service was just amazing. They let us decorate the booth we ate in with balloons. They also let us bring our own cake, put it in the fridge, and provided little plates and forks for us to eat. The waitresses were nice, a bit quiet but polite. We also got a bit loud, and some balloons were popped, but we heard no complaints from the restaurant.
The place wasn't pricey, and it was different from most. They had sit down tables, and the booths had the traditional kind where you kneel. The waitresses were wearing kimonos and wooden sandals, it really added to the Japanese feel of the place. It's only the outside that's a bit plain and bothersome because of it's surroundings.
I'd definitely recommend this place, doesn't really make a difference to me. If you're gonna have a party, have it here =)
