Staying at home is a no-go. This rule also applies in good old Europe. And what better place to start than in Brussels, the heart of the European Union (spoiler alert: we did not visit the European Quarter).
Brussels is a ca. 2.5h train ride from our new home in Bonn. Home of Belgian Chocolate, Waffels, Fries, Beer and plenty of other things that will eventually force to buy a wheelbarrow to carry your belly around.
