We wanted to try swiss hot chocolate, and we heard the most famous was Sprungli Cafe. It was very busy, with lots of high end desserts. There are a few locations, the most famous on Bahnhofstrasse. We were able to get a hot chocolate from the cafe side of the store to go. Compared to other hot chocolates, the swiss version here was very thick and had a stronger cacao taste, with a hint of bitterness. Very good, would recommend trying if you are in Switzerland. Cost, 6.30 CHF.
