Thanks Steffen and Ca_aok. I've been there twice before so know the major tourist attractions. So far, I have booked a table at the Ivy, will go have afternoon tea at least once, visit the SMWS London branch and most def. check out TWE. Shopping and sightseeing are also scheduled.
I am interested in good restaurants, whisky shops, shopping in general and sightseeing and just your personal favorite stuff to do there, it does not matter if it is mainstream or off the trodden path, just fire ahead and I'll pick the best stuff. I am not really into museums or musicals but if there is some you can recommend for a reason, I may reconsider even that

Ah, and a decent chippy would be nice as well

Ta!
