U Quina is, as far as I know, the only Asian grocery store in Kraków. It's located in a rather…read moredistanced part of Kraków, hidden in a corner of the King Square mall--Kraków's version of Warsaw's Marywilska 24.
The place is very small. The selection is definitely not on par with stores up in Warsaw. Still, you can find a lot of essential stuff there: jasmine rice, rice noodles, various sauces, curry paste, Asian spices etc. Their refrigerators stock some nice frozen seafood. On my first visit I bought a kilo of shrimp and a kilo of calamari for 35 zł and 25 zł--an absolute steal compared to what one has to pay at Alma or Smaki Świata. They also sell vegetable though the selection is meager. A large quantity of lemon grass is available. If that's what you need, you know where to go. The friendly guy at the store also showed me a few taro roots, for which I couldn't readily think of a recipe.
