Frank's Grill

Frank's Grill is a Marathon institution on the Overseas Highway, serving the kind of straightforward American grill food that road travelers and local residents alike appreciate. Marathon sits roughly in the middle of the Florida Keys, making Frank's a useful and satisfying stop on the long drive between Miami and Key West. Expect burgers, grilled items, and comfort-food staples delivered without pretension. It's the honest, working-person's restaurant of the middle Keys — the kind of place that has been fueling fishermen and commuters for years.
