I'm a big fan of breakfast buffets. What are some of the best ones in Vegas? So far I've done breakfast at the buffets at The Mirage, MGM Grand, and Aria. Out of the three MGM Grand was easily the best. The most variety and the tastiest food. I was shocked as I had never really heard anything about their buffet either way but it was so good. Aria was easily the worst out of the three (this was just last week, so it was post-renovation). They hardly had any breakfast foods and what they did have was very "meh." I've eaten at the Aria buffet for breakfast and dinner and both meals were massive disappointments. I'm pretty much done with them.
