For a quick snack in the city centre, a visit to this house of long lasting tradition is a must. The Tresniewski buffet offers little sandwiches with various toppings and egg-based spreads. From herring-onion to cucumber-egg, hearty meat or light vegetarian, spicy or mild, there is an open-faced sandwich for every taste, all priced at €1,40 each. 18 of these spreads have been on their menu since 1902, and several have been added more recently. The most popular is supposedly bacon with egg.
