Avogadro's Number

Avo's is a Fort Collins music venue, bar, and American restaurant on South Mason Street with something for most eaters and drinkers: vegetarian and vegan options alongside a well-executed steak sandwich. The 120-capacity all-ages room can host shows Thursday through Monday, with open mic on Tuesdays and a bluegrass jam on Wednesdays that gives the calendar a full seven-day rhythm. The programming is genre-open. For guests, it is one of the essential Fort Collins spots for combining a real meal with live music; for artists, the calendar's density and the room's history make it a legitimate working stage.
