There seems to be plenty of business around.
In my little burg there is McDonalds, Burger King, Arbys, White Castle, Hardees, SteakNShake, Wendys, FiveGuys, and Culvers within a mile or so for beef, plus KFC, TacoBell, and PandaExpress.
Right; I think their price competition is keeping inflation at bay (at least for now) for the value menus.
