Daquirium in Brussels is a must.
10'000 different beers from around the world over 5 floors.
Red light district near train station in the north is probably the second most exciting place to visit in the city of Brussels.

In Belgium the people are not friendly, cold and ipity, and don't want to talk or socialize, extremely authoritative people while giving first impression they are not. Deceiving…
Netherlands better, people more relaxed and like to socialize.
