A Demon bar was an establishment that specifically catered to vampires, demons and by extension humans. These bars sold alcohol as well as food favored by demons, such as blood for vampires, and was tended by demons and humans alike.

Caritas was a karaoke bar owned by Lorne in Los Angeles that patroned demons and humans. It also allowed customers to be "read" by Lorne while singing to see how their destiny was. The bar was enchanted with a Sanctuary Spell, preventing demon violence. However, there was a loophole in the spell's function as it didn't prevent humans committing acts of violence, leading to Gunn's crew holding the bar hostage until the spell was broken, allowing the demons to fight back.
