At Planet Sub, guests are handed a playing card when they order and listen for that card to be called, indicating their food is ready. The sandwich shop’s real calling card, however, is bread made entirely from scratch on the premises.
“Every Planet Sub is also a bakery,” says cofounder and CEO Jeff Klusman. “There is a dough mixer in every location.”
Planet Sub traces its roots to 1979, when Yello Sub opened near the University of Kansas in Lawrence, Kansas.
