Pull your dinghy up to the dock and watch the resident iguanas plod past at this simple open-air, tin-roofed restaurant on a rough-plank deck beside the Dewey canal. Tarpon cruise past in the jade waters below, and the to and fro of boaters also keeps patrons amused. Doubling as Culebra's favorite local watering hole and gringo hangout, palm tree trunks litter the space, which is painted in a rainbow of pink, purple, and green. With a nightly changing menu, Mamacita's down-home dishes play a part in the appeal. The menu is heavy on burgers and sandwiches, but seafood dishes include an excellent mahi mahi.
