Sans Pere is my new favourite place to have breakfast, café or lunch. In the heart of Shoreditch it really feels like a modern home. Their quiches are delicious and they have an in-house patisserie kitchen and let me tell you their cute bite-size choux and bronuts (brioche-donuts) are worth the detour.
On a hot day there is nothing better to do in London then go for a swim in the Heath ponds. You get completely transported you out of the city as Hampstead feels like being in the countryside except you're in central London?!
Teeny, French cafe with amazing pastries, great coffee and incredible croque-monsieur. Long table in the front and small garden in the back or take away and head to Highbury Fields, which is only a couple of minutes away.
