I'll preface with the fact that I am not a sushi connoisseur but I love Ru San's lunch buffet. It provides me the opportunity to try a variety of sushi along with other buffet items like the soup, salads, calamari, and deserts. The fact that the place is full every time I go there (for lunch) is an indicator that they have something going that is good. Price is right and selection is awesome. Now, I will agree with one review below that expresses some frustration with the lack of labels. Most of the time, I don't know what I'm eating but when it is so good it doesn't really matter. Ru San's doesn't contribute to my sushi 101 learning so when I travel for work and want sushi I can't carry over my Ru San experience into the more sophisticated sushi places. I'm still a fish out of water when ordering sushi (pun intended).
Go have lunch at Ru San's. It's fun with a group of four or more (of course, I guess that depends on the four).
