I was there in June and it was pretty overwhelming. They have over 300 Belgian beer available, with about a half dozen on tap. Their menu is in Dutch and French, and their beers are separated first by Belgian province, then brewer, then the brews that they make. Not knowing anything about the geography of Belgium, it was challenging to find specific beer that I wanted to try.
The whole place consists of a small front room with a bar and and a small back room with a handful of tables. Our server was great he could describe every beer I asked about and was really interested in Canadian beer and was overall excellent to talk to. If you're in the area, definitely worth it to visit!
