It currently[when?] has 69 locations open in 37 states across the US, six locations in Mexico City, and locations in Guatemala City, Panama City, and Dubai. Founded by restaurateur Jeff Sinelli, CEO of Genghis Grill, in 2003, Which Wich began with one location in downtown Dallas. It began franchising in 2005. Which Wich is known for its ordering system, in which customers use red sharpies to mark up pre-printed menus on sandwich bags. They select a sandwich from 10 categories, then choose the bread, cheese, spreads, and toppings. The sandwiches are then prepared, and delivered in the personalized sandwich bags. Guests are encouraged to draw on their bags using red Sharpies and hang their “artwork” on the community wall.
