I stopped into Which Wich in Lake Mary one afternoon for lunch. This chain once had a location in the Altamonte Mall that was very short lived, and now they have reopened here. According to the Traveler Foodie blog, there's also a Which Wich in the Dr. Phillips area. Other than that, I'm not familiar with any other locations in the area. I found Wich Which had a slightly confusing ordering system until you figure out how it works. They have numbered paper bags hanging on the wall, with each number referring to a different type of meat. Once you pick your bag, you then take a sharpie and check off all the toppings you want on the sandwich. Problems occur if you change your mind and want to uncheck something. Hand the bag over to the cashier, pay, and your bag is passed to the sandwich maker who assembles what your bag says.
