My present plans are to devote the day to the British Museum. I've only been to London twice before and as is typical for business travel, usually have just a little time for leisure. Past visits have included Westminster Abbey and the Tower of London.
Being a clothes hound, I'd consider spending time browsing the shops, but (1) I'm not a big fan of just taking up the staffs' time if I don't intend to buy, and (2) my obvious choice would be shoos but I figure that unless I want to spend at least the equivalent of $1200 (give or take a little), I should just stick to the US market here at home. Does anyone want to talk me out of those thoughts? When in Paris I bought a few ties at Charvet; is there an equivalent 'quintessential London' item?
Still haven't decided what to do for dinner on Friday night. Someplace in Mayfair maybe?
I recommend Cording's for cord and moleskin trousers, especially if you like to wear braces/suspenders. They also have some great sports and shooting jackets that you cannot buy from the online shop.
For dinner on Friday evening, I suggest Wilton's in Jermyn Street or Boisdale of Belgravia (the best place to smoke cigars with its legal, almost indoor, terrace.
