America is a land of awful sandwiches, of industrially produced, sugary bread; of rubbery, microwaved half-meats; of watery, shredded lettuce. The one city that doesn’t tolerate mediocrity is Philly. Philly’s urban density means there is a never-ending appetite for classic comfort as well as hoagie experimentation, and that density gave me the idea to do a Philly sandwich tour by bike.
