"As its name suggests, Southtown Sub serves up a bunch of different subs (and a pretty good Italian beef). But the main reason to visit this take-out-only spot in Greater Grand Crossing is for Chicago’s underrated icon: the Gym Shoe (or Jim Shoe, though no one knows who Jim is). It’s a behemoth, with roast beef, gyro meat, and corned beef all stuffed in a sturdy French roll. But the fun doesn’t stop there—it’s loaded with a messy-but-delicious combination of cheese, tzatziki, mustard, mayo, and grilled onions. Both hands and a bunch of napkins are a necessity, but it’s a sandwich that makes ending up with tzatziki-painted eyebrows worth it." - sam faye, adrian kane, john ringor
