A former Philadelphia resident said it's better than most back home. That's the one that gets repeated.

A corner of the South Side worth finding

Union Sub lives at 110 East 51st Street, in the heart of Bronzeville and Hyde Park — and it earned its reputation the only way that counts: one sandwich at a time.

What our guests are saying

Order the Philly Cheesesteak from doordash and honestly, it's better than most cheesesteaks in Philly. I used to live there. The fries are decent and it came with the good ole chicago classic RC Cola. They might get a bad rap, but I ordered this twice and it was great both times. Good pick for food
