You never know what'll be flowing at Sun King's unvarnished downtown taproom. Indy's young and hip pile in to find out, swilling brews from a cocoa-y Baltic porter to a popcorn-tinged pilsner (made with Indiana popcorn). Flights (six 3oz samples) cost $6. It's packed on Fridays, when the brewery offers cheap growlers. The outdoor patio hops in summer.
