First up: the Jubilee line. This is the royal road to fun. You want a silver train. Get on it. Ride it until you see the words “North Greenwich.”
Really, it’s that simple. The station is inside the O2. You step off the train, and bam—you’re basically in the queue for the bar. You can’t miss it. The station smells like popcorn and anxiety.
One pro tip: if you’re coming from central London, avoid the trains between 5 and 7 PM. You will be a sardine. A very excited sardine, mind you. But a sardine nonetheless.
