I've been to RAA twice now and both times I was quite happy with both the food and the service. In particular, the owner took time to tell us about the efforts made to create a specific ambience using restored wood from a barn and a special slab of wood used to make the sushi bar.
I really enjoyed the Onigiri rice balls - tried both the salmon and the eel. The seaweed was fresh (still crispy) and the rice was delicately flavoured. I also had the Negii Hamachi roll (with green onion) which was both tasty and fresh, as well as reasonably priced.
The Raa-men noodles was a tad on the salty side, but the noodles had a great al-dente consistency to them, along with velvety pieces of pork. I also enjoyed the Crab Croquette which is very different fare from most of the Japanese restaurants that seem to be popping up everywhere these days.
For ambience, service and taste...I will definitely be back at RAA again! I'm looking forward to trying other items on the menu.
