My first impression of this bar was not good. We came to Vegas for a bachelorette party and had Living Social coupons. Come to find out, there was a private party and we were told we could only stand at the bar (bar stools were removed for the party) We all hung out at the bar and had a pretty good time. The bartender was very nice and was quick to keep our glasses filled. Overall, it wasn't bad. As for the ambience, the place is small and cozy. There's a private area upstairs but I imagine you have to spend some money to be invited there. Everything else about the bar you can find out from the other reviews.
If you don't have a coupon of sorts, the drinks are $20 each. a little pricey but I'm sure it's the going rate in Vegas. I don't think Fizz needs my recommendation simply because of where it's located in Ceasar's and it's reputation. I'll remain neutral and let you decide.
