Went to chocolate No 5 on a recommendation of a friend that took me there, the place is well overrated and over priced for what you get, most coffees and deserts start at the $11- mark, so 2 desserts and 2 coffees cost me a tidy sum of $42-, wasn't impressed with that at all. Especially because the place is very basic, and there is no justifiable reason for the extreme high prices.
The surrounding decor is pretty average, and more could be done to spice up the place.
Apart for that the coffees and cares are ok, i prefer Bracegirdles chocolate. If in Hahndorf, unless you want to impress a girl with the prices, check out other more reasonably priced places, and save your money for dinner.
I hope this review and photos are helpful
