They definitely do have Ginger Ale, it's certainly not a cheap store though!

Milkbar in Krakow? Barszcz, Zurek and PierogiI'm going to spend a couple of days in Krakow in march and am looking for a good place to taste some authentic polisch cuisine.
I don't care if it's a "milkbar" or a fancy restaurant, but i would prefer one down to earth "milkbar" with nice portions.
I can't remember the name, but there's one about half way down Grodzka, just off Rynek GLowny. I've been there a few times and the food is very reasonable.Try Chlopskie Jadlo. Excellent food, huge portions.
