Look. This is my secret weapon for challenging weeks. You know, those when files build a China wall around you. This perfect butter and honey flajack, with a layer of caramel, another of chocolate, sprinklend with hazelnuts and pistachios take all the trouble away, one bite at a time. Of course, you have used more than your calorie allowance but yes, it is that good, even if it seems simple enough. Stock on those at Prêt-à-manger. And to burn the extra energy, choose in the week-end ideas below!

That’s art baby:
* On Thursday, dress 1930ies style to see the Mondrian exhibition.
* Friday, the late evening of the V&A celebrates Persia.
* A musical sculpture in Canary Wharf? Now that will make you love modern art.

Yummy time ahead:
* A speakeasy behind a sex-shop in Soho, how intriguing!
* The food market on Southbank will be all about chocolate this week-end.
* Indulge at the chocolate lab too. They even do brunches.
* The best Sunday idea ever -  a roast with a “Make your own Bloody Mary” option. And a kids club!

Take the little ones along:
* The Harry Potter studios are opening on Saturday – magic!
* Dimanche, sortez les cerfs-volants.On Sunday, go and fly a kite.

Out of the ordinary:
* Try Kicktable - an amazing way to discover new skills or share yours.
* Revise your London ABC.
* Kensington Palace has reopened, even more magical than before.
