Bertman's Ball Park Mustard (Bertman's, Progressive Field, Cleveland)

The most famous comestible at Progressive Field is actually a condiment: Bertman's Ball Park Mustard, a rich brown mustard that's been slathered on hot dogs at Indians games since the Tribe played at League Park. Slap some on the half-pound "Slugger Dog," and experience a Cleveland classic. It may sound simple – but if it was good enough for your grandfather when he watched Bob Feller pitch, it's good enough for you, junior.
