There are many great restaurants in the Savannah Downtown District and beyond: We would say casual breakfast/brunch favorites is Clary's & B.Matthew's:For a little more upscale breakfast brunch:There is the new Australian inspired Collins Quarter or the world Famous Elizabeth's On 37th(Southern french fusion;Also great for lunch or Dinner; reservations only)
For Casual lunch there is Lizzy's Tequila Bar and grill on River street(very touristy area, across from marketplace), Fire Street food(asian fusion)The Crystal Beer parlor (local favorite), Vinnie Van Go go's Pizza(very casual) or Green Truck(grassfed burger joint)
More upscale lunch:Treylor Park(eclectic Tapas),Pacci Italian Kitchen(italian)Vic's On the River(fine dining southern)
