Lavender - I assume he didn't go on the Ring then? If it's bad then it can take dh 90 minutes to get from Evere to Junction 1 in the evenings, and it can be appalling in the mornings as well if you don't hit it at the right times.
'Food was more expensive but far better choice and quality.' Agree with the former on price; totally disagree with the latter. What I wouldn't give for Sainsbury's or Waitrose here, but we do at last have some stuff from the latter.
As for choice, there isn't even a standard range in Carrefour - I can't get fresh cream in Waterloo or Kraainem, but I can in Tervuren. Crazy. The thing that Belgium does far better than UK is bread and patisserie. Can't fault them there, and coffee, beer and chocolate as well.
