Blue Sky Deli (Hajji’s)

New York City's Most Iconic Foods—and Where to Get Them | Condé Nast Traveler

"I’d argue the chopped cheese is to New York as the hot dog is to Chicago, or the taco is to LA—and if you want the OG, this is the spot for the sandwich that started a phenomenon. Expect a wonderful, hot mess: ground beef, onion, and American cheese chopped and scrambled together on the griddle, then thrown onto a hoagie and topped with lettuce, ketchup, mayo, and whatever else you want folded in—from barbecue sauce to Blue Takis. The ubiquity of chopped cheeses is part of the charm, but the one here is the benchmark." - Kat Chen
