I am going to preface this by admitting, I have never been to Ru San's for anything but the Saturday $10 lunch buffet. That being said, it's one good buffet! The sushi is pretty good for buffet and the other food on the buffet is pretty good, too. I am not going to say it's the best sushi I ever had, because obviously, at $10-- why would it be? But it's is one heck of a deal for pretty good all-you-can-eat sushi that doesn't make you sick afterward.
