Belgium is full of beer, which means that it is also full of breweries. Although its not possible at each and every one, many breweries do conduct tours and allow visitors to sample their potions.
The Dubuisson Brewery is one that welcomes visitors. There is also a restaurant on the premises so it is also to have a beer and a delicious meal before or after your tour. The place also has a small store too, so you can buy some of the beer, some unique beer glasses, trays, books and even Bush and Trolls underwear to take home with you to remember your visit.
