I really love this city and one thing we have to do always is a visit of "Miniatur Wunderland" The largest model railway in the world and one of the most successful permanent exhibitions in Northern Germany.
This exhibition is located in the old warehouse district in Hamburg, where in the past and even today coffee, tea, spices and carpets are stored and traded. There, we also discovered this experience café , where you can see how they grind the coffee - needless to say, that comes from all over the world. Hamburg is called "Gateway to the world." Did I mention that I love this city?
