i've been to many Coffee Heavens in PL and CZ - more for convenience rather than because they do good coffee - which they don't.
But the staff are indeed rather good (especially in CZ, unsurprisingly) and their leather sofas are lovely :)
Best coffee I've had recently in PL was, rather surprisingly, at the new terminal at Okęcie - where Wedel have a small cafe.
Fortunately Costa are making some inroads into the area, so a decent espresso should be available everywhere soon (i.e. not just at my aunty's, lol) and hopefully Starbucks will continue to close branches (haha).
Can anyone recommend some real Polish cafes in Krakow? I love the little cake shops in Poland where you can buy some cakes and coffee for eat in or take out. its a real treat.
I wish I could remember what it's called, but there's a really small, dark, dungeon-like place in an alley just off the main market square which was great, AND inexpensive (a year ago, anyway). I think it's between ul.Grodzka and Pasaz Bielaka, or at least off one of the streets at that side of the square, but I'd have to go there again to find it, sorry.
