What happens when you combine a zoo with German heritage, beer and polka? Find out at OktoBEARfest hosted at the Maryland Zoo in Baltimore's Waterfowl Lake Pavilion area. In conjunction with Baltimore Beer Week, John Stevens’ Doubleshot will set the tone with two sets from his Polka band. Chow down on traditional grub and wash it down with beer selections like DuClaw, Flying Dog, Harpoon, Hofbrau, Yards, Hop City, Sly Fox, Boulevard among others (subject to change).
