Well, I'm actually travelling around South America, but I brought ONE and UNIQUE belgian beer! I'd like to get rid of it, it weights and I'm afraid that my clothes smell beer for the rest of the trip in case of... brrr better not to think about it. That's for the material part. What I could offer you is, of course, an incredible course about belgian culture (and how a so small country is full of joy and happiness.... when it's not raining), a couch when you'll come to Brussels, awesome lebanese recipe, and, well, don't be too exigent!
