Friendly warning! We're working hard to be accurate. But these are unusual times, so please check that venues remain open.
Goldburger’s Allen Yelent gives fans the best of both worlds: a still-juicy center but ample crust. This pop-up’s patties are more pressed around the edges, and topped with American cheese, a little mustard, mayo and either raw or grilled onions. If you’re lucky you just might find the occasional patty melt special, where the smashed patties layer onto Bub and Grandma’s house loaf with cheese and grilled onions. You can usually find Goldburger’s stacks at Tabula Rasa Bar on the second Sunday of the month (5–9pm), but keep your eyes on Instagram for updates and additional locations.
