So, in connection with this year's MacRumors London picnic, I am looking for new shops and places to visit in Central London - especially those which fit my geeky taste and hobby. I already know about Forbidden Planet (poor credit card), the record shops in Berwick Street and Notting Hill Gate, and the Apple Store obviously. I usually spend some time at Waterstones and Foyles as well, oh, and the Covent Garden Market. What else might be interesting? Are there any other places and shops which might be of interest? Any well hidden second hand record stores?
