First of all, a chain Irish bar does not belong in the Rio. Management can and should come up with a better gimmick. That said, it would be alright in the place exuded some Irish charm. It doesn't.
I came here with a drinking buddy in July, looking for some good beer after all of the razz-squatini type drinks dished out at the i-bar. We had a coupon, so that made the beers only four bucks a piece. I don't remember what we drank, but I do remember the butterface bartender/waitress wearing low-rise jeans, clearly without underwear, walking around with a bottle opener IN the back of her pants. Then she opened up our bottles with said opener and stuck it back in her ass. This would be a neat trick in a strip club. Here, it was just bizarre.
We drank the beers and fled the premises. WTF? Go away McFaddens.
