nor do I, but you're focusing on two very specific, negative, things about it.
It had a gritty realism which every city should have - whether it be the dingy pubs with the all day drinkers, the warehouse parties in the disused industrial buildings which became the petri dish in which Acid House, and subsequently chart dance music, was grown, or the blend of small independent businesses into the sheds behind the station harking back to when London was more than a tourist destination and playground for rich foreigners.
It's now a generic, upmarket shopping area with a few decent places to eat thrown in - like you'd find in most other parts of the city, and in many cities across the world.
Soho is just about there too now, and there's very few places left in the city that haven't been gentrified. Someone who puts all this far more eloquently than me is Robert Elms, and if you've got time I'd recommend listening to his London Society lecture from a couple of months back.
