The Lobby Bar is conveniently located on the casino floor, near the check in desk/lobby...imagine that! It is one of the first bars you run into when you come in through the valet entrance doors. It has a sister bar on the other side of the gaming tables, which is larger, but the service on that bar wasn't up to par. Each of the bars had one bartender while we were there. The lobby bar is a bit smaller so it's easier for one bartender to manage the work load. The other bar is about twice as big, so you don't see the bartender as often resulting in less quality of service.
The service at the Lobby Bar was exceptional the entire day we frequented it. The bartender was quick to get our order, & quick to fill it every time.
They have a daily special: $1 mimosas and $1 bloody Mary's until noon! The restaurants don't have these specials as far as I know, but in true Vegas style you can bring your drink into the restaurant :-)
The casino bars don't serve food, but you can always grab something elsewhere in the casino and belly up to the bar to eat and get cheapo morning drinks
