I visited Karmello twice, once in Cracow and once in Warsaw. To be honest, from a place that calls…read moreitself a premium chocolatier, I expected more. In the end, this was just another café which had a fancy name to attract tourists. The coffee was quite good, especially after a long day just strolling in the city, but the sweets were not to my liking. The chocolate mousse was tasteless and basically just sugar. In Warsaw, I had a coffee and a croissant which is served with a small bowl of homemade chocolate. That was a pretty good idea and tasted good, though it wasn't ground-breaking.
In general, I like the interieur and the staff is very nice and helpful, even though they barely speak English ;)
