For the last few years, the Genki location with highest profits and lowest food costs. (A little insider info for you)
I have a little soft spot for this place, having worked there for 3 years. Cheapest edible sushi in town. Over the years, the menu has remained fairly static, but there are usually a bunch of specials you can get, but you have to ask for them. Best sellers are spicy tuna, garlic ahi, hamachi, chicken karaage. Good for a fast lunch/dinner because the food is right on the belt for you to grab, no ordering needed.
