Prague underground - London overground

I've been working on an alternative guide to Prague and recently moved to London to conceive the alternative guide to... London. As a global city, it doesn't take long before something gets spotted by VICE magazine. The next week, a city intern banker checks it out, speaks about it to his boss. Before you know it TimeOut runs an article on it; the following Friday, that place has become the place to go to for all city-like londoners. So nothing alternative then? The other side of a global city is movements, flows and changes. New things spot up constantly. The difference is indeed alternative shelf-life, but more apparent a simple opposition between underground and overground. Consider the Akropolis (Prague) and 1001 (Brick Lane, London) : same style and vibe. One's underground, the other's overground
