We visited Karmello twice on our short break to Krakow. The hot chocolate is delicious, treacly and comforting. We treated ourselves to a couple of little slabs of white chocolate too, one with almonds and one with little chewy lemon pieces.
The decor is modern and simple, people come and sit with laptops as there is free wifi and power points. It is not as unique and characterful as I like but I am a fan of more quirky places! The seats and sofas at the back are comfy. On our second visit we tried milkshakes which were also yummy and bought quite a few slabs of chocolate to take home for souvenirs. The little truffles in boxes make perfect gifts and are not too expensive either.
