Alright, some New York ones:
-Price Chopper:
Ghetto Chopper. A Google Maps search for "ghetto chopper" brings you to the one on Delaware Avenue in Albany.
-New Way Lunch (hot dog place in Glens Falls/Queensbury/Lake George): Dirty John's. Hot dogs are referred to as "dirt dogs" by locals.
-Hot Dog Charlie's and Famous Lunch (Troy/Capital District): I've heard it referred to as "hairy arms" from how hot dogs used to be lined up one's arms to put sauce on
-Six Flags Great Escape: Storyland (name before the company that is now Six Flags bought it)
-BW3: Buffalo Wild Wings. Used to be "...and Weck", hence the "W3"
-Walmart: "Smallmart" for small locations in Buffalo, specifically the Lancaster Supercenter that is smaller than a typical non-Supercenter location.
-First Niagara Center: F'N Center
-Cumberland Farms: Cumbies
