The variety of slots is decent, but most are outdated. For those who enjoy the nostalgia of old-time slot machines, then this may be a good thing. The machines are worn down. However, denominations are very good.
My favorite thing about going to Mountaineer is that it is always easy to find open seats at whatever game it is you want to play. Also, table limits are great. It is nice to be able to play $5 blackjack still. The smoking is bothersome to non-smokers. Tables frequently become dirty and stained from ashes.
Don't go hungry. They really don't have much in the way of food. There is a buffet, but it does not look appetizing enough for me to try.
