I'm taking my son on a tour of Swarthmore College over spring break. I'd like to find some just-off-campus places for lunch and dinner, to give him a feel for what the area would be like as a student (beyond the obvious appeal of nearby Philly). Can any one recommend good places for a teenage boy whose tastes run towards burgers, pizza, and steak & cheese? Looking for something non-chain, maybe a little quirky or mom-and-pop-ish. Thanks!
