Tucked down Sun Street Passage in the heart of the City, this is the commuter's dock — step out of Liverpool Street, grab a Brompton, and thread through the Square Mile without waiting for a bus. A quieter, better-kept locker than some, and handy for a lunchtime spin up to Shoreditch or along the canal. Like a few of the City docks it's a touch hidden, so check the map pin before you go hunting for it.
