The Buffet at the MGM is pretty much the best. Becky and I went for Brunch which was a perfect time because I got to enjoy both breakfast and regular food items.
Over the years I have developed a system to maximize the 'all you can eat' experience.
Step 1 - Take a lap and observe everything they have. You don't want to fill up on the first things you see.
Step 2 - Start with a sample plate and see what you like.
Step 3 - Return for seconds and load up on your favorites.
Nothing like eating 3 lbs of shrimp in the middle of the afternoon. It is so luxurious I feel like a whale.
I'm no good at gambling but I win every time I hit the buffet.
