you will see everything from shorts and flip flops to people still dressed from clubs and casinos from the night before to business casual.

Pretty much what you want to wear. Paris brunch is another great option and is $24.95 best I remember.

Dress codes don't really exist in most of the Vegas restaurants. People wear what they want to wear-everything from casual to formalwear. Most people do try to dress up somewhat in the more expensive restaurants but business casual is about it. Most people don't dress up for the brunches. No matter what you wear there are going to be those that are more casually dressed than you are and those that are more formally dressed than you are-wear what you feel comforatable wearing. You will fit right in no matter what you have on.

there isn't a dress code for buffets - jeans, shorts, whatever. For other restaurants there sometimes is a dress code, it's say on their website usually, but you'll still see people in jeans.

All you need is a wallet, clothes are optional.

You could probably get away with wearing pajamas and a bathrobe.

The only dress code I've ever heard of was the ban on wearing motorcycle club "colors" and sports team

logo products.
