Here's a little experiment for you.
Pick two cities in the UK. Load up Google and search for either city's name with 'nightlife' after it and check the images that are returned.
Is it me, or are the two sets of images practically indistinguishable? I picked 'Manchester' and 'Oxford'. You'd think they'd throw up different images, different vibes, different options for a night out.
Hell, I suspect some of the models in the ads for clubs were actually the same people.
Sad...
