Mount Athos and A&M are probably among the best choices you have in Florence. Mount Athos has decent Greek food and burgers. A&M is a pizza place and their bread and rolls are really good. If you don't mind driving a little bit go to Queen Creek (about a 25-30 min drive depending where you are in Florence). The Queen Creek Olive Mill is really cool to check out and has some good food. If you go out there The Pork Shop is also a good place to stop by.
