Which Wich has become one of my husband's favorite stops on road trips for lunch. The concept is relatively simple - you decide what your primary ingredient (type of meat, veggie) will be, grab the bag that matches your choice, and check off sandwich options... like type of bread, cheese, and fillings.
With all sorts of combinations, you could probably eat here many times and never have the same thing twice. The sandwiches were pretty tasty, although they were somewhat expensive. I'd eat here again next time we're passing through.
