When I was in Bruges I realized that the Belgian citizen it is extremely delicious but also extremely crowded with tourists, including Italians. In the evening I wanted a nice place to try good beer and feel a little at home (of others). In short, not a tourist. Many, even on twitter, have recommended this place, the 't Brugs Beertje.
I tried the 't Brugs Beertje just for the time of a beer and a thing to eat, a toast I think, one thing on the fly and then I ran away. Why? In the two tables next to mine there were two couples of Italians. For heaven's sake, I'm not one of those people who must never meet Italians abroad, otherwise they are sick, but if I want a local pub this it's not quite ideal.
Here you can find many on the menu Belgian beers, it is true, there are industrial quantities, it is the land of beers :) but you should also know that the 70% of guests who are here are tourists who have seen the name of the pub on Tripadvisor or otherwise. Honestly I feel I advise against it. Although its internal atmosphere is still quite authentic, the people inside have nothing to "envy" to any place in the Grand-Place. It must be said that in Bruges there is not much local left, everything is flooded with tourists and somehow transformed to their liking into an "international" pub. As beautiful and fascinating as Bruges is, this is one big flaw.
If I can advise you, better have a beer in the first club and then take a nice tour of Bruges at night. If you don't pay too much attention to flashes the show is guaranteed ;)
