What an great article. Lots of very cool looking places. Really interesting locations too.
Dalston, Wood Green, Bethnal Green and Spitalfields are all of particular interest to me, A couple of places mentioned are in my home borough. You're really going to get the feeling of being in the heart of London life in those places. The travel to the central London sights is going to be 45 minutes or so but Dalston is well connected with two Overground stations and a multitude of buses linking to the rest of the network.
Speaking of Dalston and Wood Green, they are great to visit to try Turkish food. Outside of Berlin maybe, Dalston, Stoke Newington and Wood Green (Green Lanes) are the best places to eat Turkish in Europe. I'm surprised the author found it difficult to find breakfast in Wood Green. There's many little Turkish cafes on Green Lanes serving breakfast. All will serve a full English breakfast as well as a Turkish breakfast. I can't name everything in a Turkish breakfast, but there's feta cheese, olives, sausage and meats and a whole host of other tasty stuff. It's a great alternative to an English fried breakfast.
