As much as Failtes can be a bit scuzzy, with drunkards everywhere, it's a pretty fun place. You're almost guaranteed to have a good time if you go with friends.
The staff are generally pretty cool and fun. They have live music most nights, and the bands are generally decent cover bands playing a variety of rock and alternative hits. They have a great selection of beers and a well stocked bar. The patio is a good size, but gets pretty crowded.
The only crappy thing I can really say is that I hate paying the 5 bucks cover... but then, somehow I always get sucked in and I do...
