Cambridge: Poles apart Why Warsaw beats Cambridge Blog Mike Levy
“A weekend in Warsaw made me think about Cambridge at night. In Cambridge after 6pm the city centre empties ready for the only true night time economy: binge drinking. The Market Square alive with stall holders and shoppers at 5pm magically transforms into a ghostly empty space one hour later. It is a Cinderella midnight moment that never fails to astonish. By dusk the Cambridge ball is over and the Prince has gone home to watch T.V. Only a lonely burger van takes up residence creating a sad and soulless image that realist painter Edward Hopper could capture.” Yeah, it’s crap.
