I'm not much of a gambler, but my wife loves the slots, though she's hardly a big gambler. The payouts, as is apparently true of all West Virginia casinos, are fairly poor. We've been there four times and each time was pretty much the same. Roulette tables (usually one, sometimes two are going) are fun. The card games are pretty lively and there are usually four or five tables of various games going. It's hit or miss as far as customer service goes. In four trips, I've been asked if I wanted a drink just twice. Player's Club is okay...you can get some nice special packages in the winter and you can build up a small amount of money on your card as you play to apply to your meals. Hotel is very nice, but recently has had to cut back on various small amenities because it has lost a good deal of money. Food is good. Very pricey.
Slots didn't pay out very well at all. Over the course of two nights gambling there, I put in about $100 on either $1 machines, or $0.25 machines. I might have won about 10% of my pulls. I'd not recommend the slot machines.
The table games are very nice, 3/2 odds in blackjack with what seemed to be 6 or 8 deck. Minimums on BJ were $15. Roulette had 2 tables, one was a $10 minimum and the other a $15. Double zero's on both tables. I didn't try craps or any other table game.
The Greenbrier is a very nice resort, the casino has a jacket requirement for patrons, but has plenty to loan out if need be. Don't bother driving to this place to gamble, it's reserved for resort guests and members only.
Cocktails run about $12, beers $6 and shots about $10
