The Catacombs Bar in the dim basement of the Hotel Boulderado is like a grab bag, with the scene and the crowd changing from night to night. Sometimes there’s live music, sometimes not. Sometimes there’s some entertainment (karaoke night, trivia night, etc.), sometimes not. Sometimes there’s a tourist crowd, sometimes more locals. The Catacombs schedules “theme nights” like Trivia Night on Tuesday, Karaoke Night on Wednesday and a DJ most Thursdays through Saturdays. You never know, till you check it out. And when you do, order a reasonably priced round and see what happens.
