Ru San's is a lot of fun -and noisy! Be prepared to be greeted by a lot of yelling when you walk in the door - and again when you leave! The lunch buffet hosts a fairly standard sushi line-up and is a great place for a quick, tasty lunch during the week. For dinner, the rolls are way more creative - try the punk rock and roll (my favorite!) and the Jana Moon. I have found ordering the chirashi at a sushi restaurant gives you a good idea of the quality of the fish, and I have to say the quality here is not the greatest. Stick to the rolls and shy away from any sashimi other than tuna and salmon. Would be a great restaurant to bring out of town guests to!
