2. Publix
Publix opened its first grocery store in Winter Haven, FL back in 1930. It is a very prominent grocery store in the south, but on just about every street corner in Florida you can find a Publix grocery store.
Around UCF, just about every person walking through there is a college student buying groceries or simply dinner or dessert from their deli or bakery. If you ask any college student, they will probably tell you they love going and getting "Pub subs" from Publix and enjoying them on memory mall before class.
