1960. As well as Old England, there is Old Scotland in rue de Laeken, kilting out men and young people. And two surviving branches of the Old Tom English pub chain. Here's the chaussée d'Ixelles one in 1908. Better than EXKi. Fact.
1920. WH Smith opens a bookshop in rue du Marché aux Herbes by the Grand Place, where French bakery Eric Kayser is now. In 1934 they moved to boulevard Adolphe Max and what is now the travel and history section of Waterstones was the English tea rooms.
The Swan, a Watney's pub in Schaerbeek, 1960s. The Whitbread depot in Molenbeek and an ad for the one in Antwerp: le stout as the English drink it. 'Its strength puts you in a good mood'. Fact.
