Johnnies Grill

Dallas
$$$$

This El Reno hut turned 1950s diner is a master of three things: breakfasts, burgers, and dogs -- in no particular order and all entirely gluttonous. Within the blue brick walls and behind the small, shiny metal counter, short order cooks drown coneys and tater tots in chili and cheese, flip sizzling beef patties, and stack them high with caramelized strings of onion and melty cheese for a burgers and hot dogs OKC's residents are happy to make the trek for.
