You can't get a drink at the slot machines. They say you can, but alas, no. I ended up sitting at the bar playing video poker, where the drinks are plentiful (as long as you're playing) and if you tip the bartender up front, you'll get special attention.
One thing I'd like to see (this goes for all bars everywhere) would be purse hooks under the bar. I'm short, so if I put my purse on the floor in front of me, I have to do this interpretive dance kind of thing to lift it up with my feet when I need it. You could hang your purse on the back of your chair, if you want to have it stolen, but I'd rather not.
