Gina's Bakery, N11 1AH
Although this is named as a bakery it is also a cafe. It makes sandwiches but also sells coffee and breakfasts and other hot food. You can take out as well as eat in.
secretlondon went here one day in March 2012. I had a coffee and a croissant. I ate in but there are also tables outside on the pavement. It was fine.
