[4] Which Wich is known for its ordering system, in which customers use red Sharpie markers to mark up pre-printed menus on sandwich bags.

They select a sandwich from 10 categories, then choose the bread, cheese, spreads, and toppings.

Sandwiches come in regular (7-inch), large (10.5-inch), super (14-inch), spinach wraps, and lettucewiches sizes.
