About Donut Gallery Diner
KB institution — over 40 years in the back corner of Harbor Plaza, run by the same family. Breakfast and lunch all day, fast and friendly, fluorescent-lit, the kind of place where the regulars know each other and the staff knows everyone's order. The donuts are the namesake but the breakfast plates and Cuban-American lunch are what locals come for.
