When I moved to Charlotte about ten years ago, Showmars had about ten locations.  Now they have 25 or so.  Probably more.  They serve a variety of burgers, on buns and on pitas, and gyros and chicken as well.  They also have a fish sandwich, though I've never tried it.\n\nThe food is good and the price is decent.  I guess some people like it or they wouldn't have as many locations as they do, but I've never found anything especially outstanding about the place.
