Not the most exciting place inside, but a lovely rooftop area which not all that many people seem to know about, 2 mins walk from Old St station. If it's packed then The Red Lion is just up the road.
A winding side street that links hectic Oxford Street and Tottenham Court Road, Hanway Street, with its odd mix of old-style Spanish flamenco bars and second-hand vinyl stores, is a bit of an anomaly. I’ll be surprised if they all withstand the Tottenham Court Road redevelopment but I hope they do.
