The 'Z's stand for 'zupa' (soup) and 'zapiekanki' - a filling Polish fast food specialty that is essentially the bottom half of a baguette with mushrooms, cheese and the additional toppings of your choice. This is definitely the place to try one, as the bread and other ingredients are actually fresh, not frozen - quite a novel reinvention (sadly) of this local street food staple. As for the soups, they change every two days and can be ordered in three sizes; during our visit a spicy chilli, apple-onion, split pea, and bean-bacon were on offer. Wrocław's fast food culture is steadily improving, and this is one of the places leading the charge.
