To call the ambience at this Humboldt Park spot no-frills is something of an understatement—don’t expect much more than a few banged-up two tops and church hall-style chairs. Dig into the beef sandwich, though, and you’ll quickly forget about the cheerless digs. It’s tough to point to one single element that makes the sandwich here sing. Instead, all of its parts come together just right, making for a perfect balance of flavors: The oregano-laced jus fuses deliciously with the giardiniera oil as it seeps into the bread and the pepper heat cuts through the supremely savory beef, leaving your lips with a lingering tingle.
