Greatest American Hot Dogs (CLOSED)

This Rockville spot really lives up to its name thanks, mostly, to its most popular offering: the Maryland Dog. Forget typical condiments like ketchup and mustard, this char-grilled Vienna beef dog is served on a butter-toasted steamed bun and gets loaded with house-made four-cheese mac and cheese, lump crabmeat and scallions. If you’re feeling adventurous, swap the beef out for a half-smoke, turkey or polish sausage.
