Antwerp has a large number of traditional Beer Cafes- similar to the Dutch Brown bars.
Many have impressive collections of delicious Belgian Beers over 60 types is not uncommon!
A draft beer can cost less than a coffee!
The real gems are the many unusual bottled beers from smaller breweries, BUT beware some are VERY strong 8% + is not un common!
Try to sample the many different styles of beer and avoid the generic bland lager and give your taste buds a treat see
