This Times Square seafood super-shack is something of a theme park for fans of Tom Hanks’s 1994 film. Bubba Gump’s shrimped-out menu runs the seafood gamut from a poboy to stuffed shrimp to a mess of fish and fries called Boat Trash. Buzzing, bustling and fun for kids, Gump’s brings a bit of down-home Hollywood charm to Broadway.
