We had been recommended Cafe Kafico as the best hot chocolate in Prague. We stumbled upon the cafe, when was looking for John Lennon’s wall rather than the cafe. The hot chocolate was a good thick chocolate. However the next day we found better, on the road up from Maostranke tram stop up to the castle. It was called Prague Choclate bistro / Prazska Cokolada. A very thick flavoursome chocolate.
