My first visit here was in July 2011. My husband and I were moving in nearby. We were able to walk in at 730 pm and get seated. Unfortunately, they are between 2 larger restaurants in a strip mall. We chose to come here because it was quiet and relaxed. The service here was great. You are greeted immediately, and sat ASAP.
It is the only place I've ever seen that has DEEP FRIED SUSHI! If you go, TRY IT! I know, that's so "American" of me, but trust me, it's a good savory meal.
The prices are consistent with the area. We can get 4 sushi rolls an appetizer, and each roll comes with Miso Soup - still pay between 40-50. Coming from the DC area, this same meal would be much more expensive closer to the city.
Try it. you'll fall in love.
