Three things on the menu: a cheeseburger, a double, and fries, the same short list this counter has run since starting out in the East Village in 2021. Smashed patties go onto a squishy Martin's roll, and the stack gets onions cooked down on the flat-top, pickles, a slice of American and a creamy house sauce, with an Impossible patty available on any order. The Frankford Avenue shop opened in late summer 2026 as its first in Philly, and a second is already open on Walnut Street in University City.
