... try ordering a good Rioja or Malbec in France
Very thruth ! I'm french and live in Madrid. I was never been able to just order a good Rioja in Paris. Nor a "ibérico" ham. They just bloody don't know what it is. Not even tried with a Ribeira del Duero.
That's indeed what I love about London. You find whatever you want almost everywhere.
Ps: and all those clichés french people have about England, that the food is crap and the girls are hugly and dress like bags are completly false. Girls are gorgeous and hornies, food is excelent everywhere, even in the remote Devon that I love (I wouldn't mind having a house in Devon). There is a lot to like about England. Well, except the climate maybe...
Ps2: very strange, in Madrid is rather easy to find british products in local supermarkets without having to go to a "british pub or specialized drugstore".
