Lots of traditional charming country pubs around the area, but it can a bit hit and miss. A really friendly one with amazing food (and a unusually large veggie selection…) is the Beehive in Epping Green; close to the Great Wood. It's friendly enough you dare going there by yourself with the paper and are not at the mercy of local rubbernecks ("the rubberneck" = person who stares at strangers without any sign of guilt)
I discovered this hidden gem by pure chance when i explored the area in one of my lunch breaks. Rochelle Canteen is hidden away behind the walls of three former victorian schools on Arnold Circus in London's Shoreditch. The atmosphere, upon entering the ground, is relaxed almost tranquil. The canteen itself is situated in the old bike shed and the kitchens' size almost belies it's output. The food is distinctively modern British; run by Arnold & Henderson, a household name of britisch cuisine. The guests are local creative types so that the atmosphere is more relaxed then anything else. In the summer you can also sit outside.
The Almeida, in Islington, is a small theatre with big influence. It's an intimate place to discover groundbreaking theatre and get up close to some of Britain's leading actors. The cafe/bar across has a constantly-changing tasty menu, relaxed atmosphere and free wifi. Open all day and great place to spend time even if you're not going to catch a production.
