National Supermarket, formerly Unidos Supermarket, is an independently owned and operated grocer located on N. Armenia Ave just north of Waters Ave in Tampa. The store sells a wide variety of international groceries, and specializes in Latin-American food and items. The store has an in-house bakery, butcher, and hot food restaurant serving made-to-order dishes like Cuban Sandwiches, and the store itself is as large as any national or regional chain grocery store. There is also an onsite jewelry repair service, where customers can have items repaired while they shop.
