Shops in Belgium.

Hi all. Did a serch here but couldn't finde anything so I hope some of you can help. I'll be going to Belgium in a few weeks for work, I'm off a Thursday, and would love to buy a small (maybe a larger) stock of lambiek/geuze and bring home. I did some searches online and all the stores I found was in Brussels, I'll be working in Ooestende driving from Denmark. I rather not go to Brussel centrum since I belive it can be hard to find a parking spot, but don't minde driving a detour to get there. I have most of the lambiek breweries attached on my Google maps (want to cycle the Tour de Gueze at some point) but can't seem to find anything if they sell directly from the brewery. If this dosent work, I'll try and write an email to the different breweries and ask them, but I'll try here first since I hade good response from another beer forum before. Thanks all and have a good day.
