This may not be much of a secret but deserves a mention. I find it hard to go anywhere near this place without having to go there. Freshly baked Beigels hot salt beef and it never closes, 24 hours a day 7 days a week.

Where 1984 of George Orwell got its inspiration from, the craziness of a real ministry of propaganda. 

Raisin bread and sausage rolls; plus madeleines, palmiers, financiers, croissants, and cinnamon buns for breakfast with a Parisian jazz soundtrack

Traditional Punjabi restaurant that has been serving aromatic, spicy dishes since 1972. Bring your own alcohol.

By far the best bagels in London, they are open 24 hours and being just down the road from my flat a bit too local. It is run by a man called Mr Sammy, who doesn't muck about with portion size. It is well worth a visit especially for their smoked salmon and cream cheese speciality.
