If there's one activity you must do when visiting Belgium, it's this waffle 'n beer workshop in the center of Bruges! (note: they also have workshops in Ghent and Brussels.)
The workshop starts with a little beer tasting and while you're baking waffles you can get as many drinks as you like. Everything is included in the price. (Also non alcoholic options are available!). We had the best 1,5 hour of our lives!
The price for this workshop is 45 euros.
