Re: Herpa Shops in Brussels
-Serneels toy store, located next to the Steigenberger hotel (ex. Conrad), Place Stéphanie
Metro station Louise (lines 2 and 6) or Tram stop Stephanie (lines 92, 93, 94 and 97)
-Autoworld Museum shop, located inside the museum near the Cinquantenaire/Jubelpark. Station Merode (Metro 1 or 5, tram 81 or bus 22, 27, 61 or 80).
Both shops are very expensive.
-Technohobby Halle, located in the city of Halle, can be reached by train (around 15 mins from Brussels. All trains to Halle departs from Brussels South (Midi), Central and North station (approx 4 trains a hour). Shop is lacated at a short walking distance from the station.
-Eurojouets Wavre, located in the city of Wavre but can only be reached by car.
In Antwerp (I don't know if you are planning to visit the city):
-Hermann Verbosschen (or something similar), located near the Groenplaats
-There was a really nice shop but they don't have a showroom anymore.
Also, make sure to visit the Aviation hall of the Army museum (also civil aircrafts).
Entrance is free and located in front of Autoworld (see above)
