Pyzy, Flaki Gorace! ★ 4.4
Why locals love it: The Praga pyzy room serves dumplings in jam jars under fluorescent strips for under 20 zl, the kind of working-class Polish meal Old Town tourists rarely cross the Vistula river to find.
Tip: Cash works fine. The flaki tripe soup is the second-order if pyzy is not enough.
