Having a meal at a Bar Mleczny / Milk Bar could be a real tourist attraction, seriously, I'm…read moretelling you. It's definitely something new and exotic for someone who has never experienced simple Polish home cooking. The prices are generally lower than at regular restaurants, and the portions are big. Don't be too fussy, just enjoy because everything is always freshly made and delicious.
For example, the Bar Mleczny Nowotarska 4A in Zakopane is actually one of my favorite places to get a hearty meal. After dinner, we are always satisfied and full, ready to hit the town, or, first, have a siesta ;).
The order process is always the same. Look at the menu, which is usually on a board, order and pay at the counter. This particular spot is always packed, so you should expect a little wait. Your receipt has a number that will be called out once your order is ready for pickup.
Sometimes, a "Danie Dnia" / "Dish of the Day" is offered. This is a daily special where, for a set price, you receive soup, a main course, and salads, (perhaps a compote as well, it depends on the place).
For example, on the first day we were there, the 'Danie Dnia' was cucumber in brine soup with rice, pork loin braised in mushroom sauce, potatoes, and a raw vegetables salad assortment, all for 35 zł (about $9.50).
Afterwards, it's always polite to leave your dirty dishes at the window located in the last room.
