I am going to have visitors, around 10 persons, on this Saturday evening, so I need some help for a restaurant. The visitors are not personal. Thus the air shouldn't be too informal. I am looking for a Not-too-formal and somewhat relaxed place where dinner is served and the various Belgian beers can be tasted. And It should be around Grand Place or Fish Market. In summary, again, 1. Around Grand Place or Fish Market 2. Dinner and Various Belgian Beers 3. Not-too-formal 4. About 10 persons I will appreciate if you recommend some good restaurants matching the above conditions and also some delicious dishes there together.
