JACK FLATS – American
Half a block into the Duval Street crush, up at 509 1/2, Jack Flats has been Key West's sports bar of record since 2003: screens everywhere, more than fifteen taps, and air conditioning that counts for a lot in August. The kitchen runs comfort food at scale - pretzel bread, tater tots, coconut shrimp, buffalo shrimp, a grouper sandwich, Jack's meatloaf, Alice's pot roast. Everything is made to order and the portions are generous, from lunch until very late. Locals and visitors end up at the same tables. That is the whole trick.
