We just got back a week ago. Only thing I can add is that
It seemed to be a trend that when the Asian restaurant was closed (1x per week) quite a bit more Asian offerings were at the buffet. I think it was a Wed night. Maybe. When Italian restaurant was closed (1x per week), quite a bit more Italian offerings were at the buffet. That was a Monday night. I think.
Not an exact answer to your question, but a little 411 for this thread
