Hey Andy I thought you were in Shanghai! Not France!

Cite Bourgogne? Qu'est ce que c'est que ca?

Am I "en France" (literal translation - in France)? Non (no).
The simple explanation is that this building has been built in an area of Shanghai known as The French Concession but I don't know when. Parts of Shanghai were divvied up and ceeded to other countries such as good old Blighty, The French, the USA and other countries and the Chinese government were obliged, by the use of artillery and gunboats bobbing about on the Huangpu river, to rent these areas to foreign powers.
The British and Americans and all the other nations eventually just lumped their bits all together and called it The Shanghai International Settlement. The French, as per, kept their bit separate and went about doing what they always do ie. exactly what they bloody well please and more or less the opposite of anything anyone else wants them to do. Whatever it is. Even if it's sensible. Like women.
No doubt their typically haughty Gallic preference for keeping themselves to themselves went down rather well with everyone else in 1920's Shanghai. It meant they could get on smoking opium and shouting at Chinese people in English, without bumping into Guy de la Nez or whatever his bloody names is, looking down his enormous French conk at one.
These days it's probably the nicest area of Shanghai and home to many expats. So it is now full of Oirish bars, British bars and other bars which think that just because they have a flappy velvet curtain over the doorway, play Bryan Adams and turn the lights down a bit, they can sell a bottle Tsing Tsao (really quite tasty) for £3! When it only costs 40p in the tatty shop next door to where I live.
I ask you.
Not only that, they're full of exactly the kind of people you try to avoid in London.
