Friendliness and casual comfort define the sports haven Billy's Tavern in Davie. Located on the tail end of a strip mall, Billy's gathers Pittsburgh enthusiasts and football regulars whose hearts pump black and gold blood and whose eyes are glued to the large projection screen on Sundays. But Cleveland Browns and Baltimore Ravens fans don't have to fret, the welcoming environment extends from the customers to the waitresses to the bartenders. The pub only serves beer and wine, in addition to a full menu. But don't come here for the impressive selection of exotic brews or a perfectly blackened grouper. Instead head to Billy's for all the familiar faces during a happy hour that runs 3 to 7 p.m. Monday through Friday, and 1 to 6 p.m. Saturday and Sunday.
