Vous n’êtes pas loin de Bruxelles, et à la grande époque du ZX Spectrum, je trouvais tout là :

The best English-speaking bookshop in Brussels is Waterstone’s, located at 71-75, Boulevard Adolphe Max, a stone’s throw from City2 Shopping Centre and Inno Department Store in the northern part of Rue Neuve. There is another big English bookshop, Sterling Books, next to the southern end of Rue Neuve, at 39, Rue Fossé aux Loups (« Wolves Ditch Street »). The EU quarter’s place to to go for English-language publications is The English Shop, located at 186, Rue Stevin.

Cordialement.
