For my long weekend in Vegas this was my favorite hangout. It was in the hotel we were staying at, Treasure Island and an obvious choice. We chose the hotel partly because we heard this place was good.
Hotel guests get in free, but that doesn't matter because there are always promo people handing out comp cards around the casino floor to get in free.
The music was good, the layout was great and there was dancing a good social scene. The outside bartenders were friendly and put on a good show. You could also see the Sirens of Treasure Island show which was entertaining while sucking down delicious drinks.
If I go back to Vegas this is where I am hanging out.
