Hidden away and hard to find? Check. Unpretentiously adorned and decorated? Check. Really good food that tastes homemade and is priced relatively low? Check. John's Backyard Grill ticks all the boxes. Located in the back of a Chevron gas station in Far North Dallas, John's offers mainly hamburgers and tacos, along with breakfast burritos, tortas and a quesadilla platter, but the burger is the star here. Juicy and thick, it captures exactly the flavor of that old Weber kettle grill from late July summer backyard patio cookouts, and at $8 (which includes above-average fries), it's a bargain.
