We are going to be in Brussels next week, and I'd love to know of a good spot to enjoy one of the terrific beers and do a little people watching. Last time there, I randomly picked a spot on the Grand Place, but I am sure some are better than others. Considerations: I'll take good price over good decor,and I will have a 9 year old with me. It's great fun to arrive somewhere new and lead my family to a great spot recommended by a local! Thanks for suggestions.
