My wife and I were at Rouge on a Saturday night at 7:30 before a show. The place is smack in the middle of MGM, and is very chic and trendy.... or whatever the antonym of "divey" is. It was not very crowded, but since Vegas doesn't really get moving until after 11 PM, I was not all that surprised.
I had an issue with using a comp I had here which they were not able to resolve, but they dealt with it in a friendly manner so didn't ding them for this in the overall review.
I'm giving them a three, only because I generally prefer paying less than $6 for my bud lights. But maybe one day when I'm rich and famous and running out of places to spend my money I'll be back. Until then, I'll just get my drinks free at the one armed bandits.
