Sushi Maru is a typical Japanese restaurant with its main focus on the sushi boat in the middle. I recommend sitting at the boating area because that's where all the action is. The prices here are incredible(!), and the low prices are not inversely relative to the quality of the food - I thought the food was absolutely delicious. The salmon sashimi tasted fresh and smooth.
To give an idea of the prices - the two of us ordered a two-item bento box (chicken teriyaki and sashimi which came, in addition, with 3 california rolls, soup, salad, and rice) and about 5 plates from the boats. The total, with drinks, came out to just $27.
The service was prompt and not incredibly exception, but they were always polite and efficient. One cannot ask for more than that in such an establishment. If you're jonesing for some Japanese food but don't want to take out another mortgage to afford it, I recommend Sushi Maru!
