You'll find it as a soup 'kapusniak', sliced up for salads, pickled for sauerkraut, the foundation of bigos, or stuffed with rice, meat, or mushrooms as 'golabki'. Potatoes are another, which show up in the pierogi, as a side to a meat dish, or fried and served with sour milk as 'placki'. You can find a McDonald's on every other street corner in Warsaw, or a Pizza Hut, or a KFC if home is what you're looking for. For a touch of the middle-east, seek out the stands on the corner of ul. Use the 'number of people rule' and patronize those that everyone else is.
Poles like to drink, and usually they like to drink chilled vodka .
So don't ever try to keep up, unless you've had lots of practice. Most nip it back neat, with a chaser of some sort, but mixing it with orange or apple juice is also quite popular. If you're looking for something softer, beer is on tap everywhere and the national brands 'Zywiec', 'Okocim', or 'EB' are worth a taste. If you didn't, don't . Since even Polish salads often contain meat, the decidedly vegetarian should look for 'potrawy jarskie' or 'bez miesne' on the menu of the finer restaurants, or seek out a 'bar mleczny'.
