Just outside the front entrance of the Castello Sforzesco lies an otherwise unassuming food cart, but as you get closer you will find that the wall is plastered with one sandwich after another, each perhaps only slight different than the last. The best part is that the prices are perfectly reasonable, and as you get to the end of the menu, you will find that they also offer alcohol, such as Limoncello. When you have (somehow) digested the monstrous menu, place your order at one side, wait patiently as they call your number (and try to determine if it is you, since they announce it in their native language, and you only speak English), then take your goodies and have a small picnic while watching the fountain in front of the castle.
