Thanks for sharing the info about the large buffet.
Personally I do not do buffets too often. It is not because I do not like them. It is because I cannot eat too much without getting very sleepy. I tend to get a little bit of everything and I end up getting very stuffed and totaled for the day.
I have done some of the buffets in Vegas and no doubt, if you like a lot of food and variety, that is the thing.
If I were at a place that offered 500+ different things, I would be useless for the entire day.
