Head to Edgware Road, otherwise known as the Mecca of Middle Eastern food, for a Shawarma at Cafe Helen for just £4. The lamb is absolutely heavenly. The meat is marinated in spices (nutmeg, cardamom, cinnamon) and lemon juice overnight before being threaded onto a large spit, which means it's not your typical greasy, after-hours drunken kebab.
