The best thing about any charity shop is that you never know what you are going to find. I have a well tested route around London that includes all of my favourite charity shops. This Oxfam has a great selection of books and often turns up some interesting clothes too.
You could call me biased, given this is the 3rd Highbury restaurant in my list, but if you're doing so then you've clearly never tried the Biang Biang Noodles at this unassuming little BYOB gem
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.
