A really nice quiet place. I play poker, and they offer daily tournaments with relatively low buy-ins. After the tournament, there's usually a €1-3 cash game running. Much better offerings than in the Vienna casino. I'm not a slots or blackjack/roulette player, but they offer those as well in a nice environment and not crowded. There's a well-stocked bar and friendly staff. Definitely worth the short drive/ride from Vienna.
