Not sure about the food, since all I tried were the Belgian frites blanched in beef and duck fat, and they turned out to be nothing special. But the beer selection is pretty good. Especially the cellar menu (five kinds of Cantillon!). Many beers are exclusive to the place only and some of them they have in different years, so you can do vertical tastings.
On the downside the service was a bit slow and the patio is just a fenced off patch of concrete jammed in between two huge office buildings, so there's not much to look at.
But I will definitely recommend the place to any beer aficionados, and be coming back myself.
