I've never been to Ru San's for anything other than their lunch buffet, which is to say in few words - an experience. However, I have made the pilgrimage from my office in Pineville more times than I like to admit to take part in the great sushi gathering. All in all, the overall experience is always a positive one. It is always busy, but the staff always does a good job with drinks and turning tables to handle a mounting crowd. The advantage of not having the sushi made to order is you can get in and out with a sizable crowd in a decent amount of time. Also it allows you to try a lot of different sushi pieces. I will say that it is difficult at times to know what you are eating as nothing is labeled. Also many of the rolls tend to be simple or are deep fried. In the end, you can always expect decent sushi in high volumes for lunch. Also try to show up early to avoid a wait.
