This bar is located in the brand new exclusive (aka expensive) Mandarin Oriental Hotel in MGM's City Center. This entire hotel is unbelievably fancy and you'll notice as soon as you walk into the lobby. The bar is on the 23rd floor and has glass walls with spectacular views of the strip. Our martini's were $20 each, but they were totally worth it for the experience (plus we got snacks). We only stayed for one drink each, but would definitely go back (for one drink). I'm not sure about the dress code, but I'd dress nice to be on the safe side. I would give it 5 stars for ambiance, service, and the quality of the drinks, but because of the extreme prices, I'll give it 4 stars.
