Not the most exciting place inside, but a lovely rooftop area which not all that many people seem to know about, 2 mins walk from Old St station. If it's packed then The Red Lion is just up the road.

On Burlington Gardens in Mayfair, Cecconi’s is a modern-day classic Italian restaurant open for breakfast, lunch and dinner, seven days a week. Cecconi’s serves handmade pasta, seafood and dishes from Italy using the finest ingredients. The restaurant has outposts in West Hollywood, Miami, Istanbul, Berlin, Barcelona, New York, and Mumbai.

Rochelle Canteen, established in 2004 by Melanie Arnold and Margot Henderson, is housed in the converted bike shed of the old Rochelle School. Rochelle Canteen is one of my favourite restaurants in London for breakfast, lunch and/ or dinner.
