9:00 p.m. on "cnn parts unknown" anthony bourdain heads to london. here we are in london, again, but this time is different. england has just voted rather unexpectedly to leave the european union and the effect here in london, anyway, has been tectonic. >> they have really shone a light on how divided the country is. >> this is a city where even in the best of times, the drinking can take on an edge of desperation. but never so much as now. is it the end of the world? >> it feels pretty bad. when the tough gets going, we want to get out and just look after ourselves. it's so selfish. >> like the whole city has had a nervous breakdown. in times of uncertainty i like to turn to my old friends.
