I went to Caramel because I heard that it was great. It was a nice, simple, very small lounge. I was surprised at how small it was. I had the Oreo martini, which cost $20. I could care less about drink prices, and don't mind paying a lot for drinks in Vegas, but $20 was a bit much for a so-so martini with Oreo crumbs at the bottom. Or possibly Hydrox - who knows?
Love the Bellagio, not wild about Caramel. Take the ten steps to the Sports Bar, put $20 in the video poker machine and get a free martini instead. The bartenders were much friendlier at the sports bar, too.
