It looks at the night life and what is occuring both from a European and an American perspective. It talks about specific places, that many can probably relate to. I used this for my dissertation which was about different culturally based bars in England. Although it doesn't go into a huge amount of detail about the effects of different culture/nationalities, it does go into a lot of depth about the actual culture of a night bar or restaurant.
Overall a very interesting read - worth getting if you have any interest in what has happened and what is changing in nightlife scenes!
