The ground floor is a large chocolate shop ( the largest chocolatier in the world), with wonderfully crafted chocolate replicas of Berlin sights. They sell many packaged chocolates which make wonderful presents, and a delightful selection of exquisitely finished chocolates for self selection. However a real treat is in store when you take the lift to the first floor restaurant. A wonderful selection of hot chocolate drinks, ( as well as other things) and fabulously presented selections of cakes. It was seriously hard to make a choice! A cake and a drink came to approx 10 euros and was well worth the money. The service of course, was very professional.
