gluten free products in Brussels
Yes, the larger two grocery chains Carrefour and DelHaize carry them. DH even has it on the web so she can pre-view what is carried and what the label looks like.

Uh...keep in mind, opening hours are well defined and not deviated from so plan ahead.
Not really a problem I would think, these stores are all over the place and the larger ones are easy to find.
