The Iron Horse is okay for a cardroom. The main "casino" has about 14 tables (poker, blackjack, etc). The restaurant is average, as is the bar. The Iron Horse does have a few pool tables if you aren't into gambling. If you are looking for serious gaming action, you'll probably want to check out another cardroom.
PROS: Cheap drinks - Location - Plenty of parking
CONS: Small - Dark - Boring
