This review is for the all you can eat sushi lunch.
While the sushi was continually stocked, there were not labels as to ingredients (there was a lot of I think that looks like tuna conversations going on). On top of that, there weren't designated serving utensils for each different roll; an issue that irked me because of contamination or folks with food allergies (and irked my friend who is allergic to gluten even more). The sushi wasn't bad, in fact, I was surprised at the size and quality for an all you can eat situation (I expected the quality to be of a much lower caliber). However, the sushi wasn't great either; I was disappointed that I didn't quite know what I was eating (because it wasn't properly labeled); there were far too many tempura flakes; and several rolls had this sticky, sweet (in my opinion, not tasty) barbecue type sauce on top.
I left Ru San's full (an expected all-you-can-eat and sushi combination) but I'm not sure if I would go back when there are so many other sushi places in Charlotte with, in my opinion, better sushi.
