If you're looking for something to do this weekend or anytime soon until next Sunday, I would thoroughly suggest you head to the Chanel exhibition in the Saatchi Gallery on Kings Road, London.
It opened on October 13th and it's only around until November 1st so head down as soon as possible. Be prepared to have a long wait, I went last weekend on a Sunday and waited an hour and a half! It's not often that Chanel would offer a free exhibition so it's something good to do at the end of the month when you're waiting for payday. Spanning all three floors, there's a whole room dedicated to the Chanel No.5 and it smells divine! Another whole room with portraits of the muses on the wall as well as the dresses many muses have worn recently.
Head down to Kings Road one day, maybe try to go on a weekday if possible so that it's quieter and pop into the Good Life Eatery for lunch while you're in the area too. Or also, go to Polpo in Duke of York square which is directly next to the Saatchi Gallery!
