Best Bar to actually be 21 at: Frankford Hall 1201 Frankford Ave. It’s worth venturing out of the normal Center City haunts up to Fishtown in northeast Philadelphia for Frankford Hall. Take the Market-Frankford Line straight up to Girard and find yourself in front of one of Philly’s only beer gardens. Make your hamburger, sausage and hot dog orders at the window and take it to a picnic table outside or head indoors for seats and a game or two of jenga. Do it right, skip the bottle and get your beer in a giant stein.
