It must not have been good days for them or something, but the times I went to this restaurant the waiters and the person who I believe to be the manager were quite rude. I never encountered a problem like this at other Flat Top Grills. I do like eating there because of the atmosphere and food, but it's just annoying to have to deal with them each time.
Ah, well. Besides the service, the food is decent. Not really clean around the buffet area, though. And the bowl that you get back may not be the delicious creation that you think you made (I mean, I personally don't really know what I'm doing when I pick out each food item). I'd say, go there only if you're really feeling the need to apply your originality. And good luck...
