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.
I grew up in Brighton which is full of cheesy bars like this. If you can handle being surrounded by multiple screens playing Kylie at full volume, its pretty much the cheapest bar in central london. The cliental is so varied its great for people watching and completely un pretentious.
