Trip to Belgium

I'm going to beer heaven, though being a hop head it might just be beer bliss but I'm still excited. I'm really looking forward to it and if anyone has any must tries while there let me know. The challenge, fitting as much in as possible in 3 days. The plan at this time is to get a beer in the airport before grabbing the luggage. I'm not drinking Stella, and would like to know if the airport bars have decent beer.
