Barcelona, Spain. Chocolate Museum. Tickets are made of chocolate, packaged with five-star red flag, and entered by two-dimensional code (6 Euros/bit) with the ticket brushed. The museum is full of chocolate sculptures, exquisite and beautiful. This is a paradise for chocolate lovers. The second floor can also be made by itself. After the visit, a cup of hot chocolate (small cup 1.7 Euro/cup) is sweet, thick, happy and reluctant to leave.
