One of the best places in the world to see left field, experimental and creative new music which sits outside the realm of the mainstream. It should be cherished.
I wish i went more often...Some highlights of mine include Midori Takada and Acid Mothers Temple.
The many book stores dotted along this strip can provide hours of inspiration. Aside from those selling new books, several specialise in second-hand and antiquarian books.
I grew up in Brighton which is full of cheesy bars like this. If you can handle being surrounded by multiple screens playing Kylie at full volume, its pretty much the cheapest bar in central london. The cliental is so varied its great for people watching and completely un pretentious.
