If you like some nice cool beer, portuguese sweets (the once with yellow custard inside) tasty and affordable sandwiches, good strong coffee and football, at all hours. Max Snack Bar is worth checking out.
London institution, a magical place to have tea and cake and a perfect spot to watch London Soho life unfold before your eyes. The quality is always superb, the staff are friendly and human and the landladies Michelle and Tanya are part of what make this place and London so magical. A little gem that is a must on anyone's visit to London.
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
