Best Grilled Cheese in the U.S.
Five Guys Burgers and Fries, multiple locations
The national chain keeps its menu spare with messy burgers and fries cooked in peanut oil. As an outlier, its grilled cheese makes innovative use of ingredients on hand. A hamburger bun is inverted, so it's flat-side out, coated with mayo, and stuffed with Kraft American cheese before getting smashed until golden and seriously melty away from the burgers on the bread-only griddle (so it's still vegetarian).
