This Creve Coeur storefront along the busy Olive Boulevard corridor is home to the first St. Louis location of the Chicago-based Potbelly Sandwich Shop chain. Potbelly doesn’t really have a gimmick. It just turns out decent toasted deli sandwiches — nothing more, nothing less. Signature sandwiches include “A Wreck”: salami, roast beef, ham, turkey and Swiss cheese on crusty white (or multigrain, if you prefer) bread. You can doctor your sandwich with the standard arrays of toppings and condiments. Don’t miss the freshly baked sugar and chocolate chip-oatmeal cookies.
