I usually avoid chain restaurants like the plague. The blandness and corporate atmosphere put me off. However, in an attempt to find a quick meal before a play downtown we discovered Which Wich on the basement level of Block 37. I fell in love with and now it's too late. One of the reasons I like Which Wich, is because every sandwich is unique, so even though you are eating at a chain, the sandwich you eat is designed by you.
Which Wich is known for its unique ordering system, in which customers use red Sharpies to mark up pre-printed menus on sandwich bags. Select a sandwich from one of 10 categories (based upon the protein used in the sandwich, turkey, ham, seafood, etc), then choose the bread, cheese, spreads, and toppings. The sandwiches are then prepared, and delivered in the personalized sandwich bags.
