The Tyber Creek Pub is one of the more enjoyable after-hours options available in South End, with an authentic Irish touch. That touch is complimented, of course, by the large screens to watch sports on and the dance floor upstairs. The food is hearty and filling, but most people are there for the beer, including the ubiquitous Guiness on tap. There's live music Thursday through Sunday, so call ahead to find out who's playing.
