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.
A slice of Scandi in the heart of London. Great for lunch, with all the meatballs, salads and classic Scandi foods you could want, along with a great little deli shop too.
