If you're picky about your drinks, then it might not be a great deal. I'm a red wine guy and my wife is a frozen rum-n-strawberry girl. She's completely s.o.l., and I have to catch the drink tray before it gets too far out the kitchen door. They only make a few kinds of free drinks, and they're all small.
Let's see if I can remember what's on the trays... red wine [probably merlot - eh], champagne or asti, a white wine [chardonnay, double-blah], a whiskey sour, perhaps?, and a few other things I don't recognize. Others will probably know.
Unless you get there real early, you can't catch any of the horse doover trays that haven't been mercilessly picked over; I honestly can't tell you what food they serve. I've never seen any of it.
I also can't tell you what kind of entertainment they have -- nondescript to say the least. We've always spent most of our time trying to find a place to sit and order my wife a frozen rum-n-strawberry something. And then it's over.
But it's an experience, and if you're into collecting experiences, this is one.
