It started when we decided to follow up the Monopoly Pub Crawl with another classic London concept - the Circle Line.
We weren't the first to have a go, but spurred on by success, a year later, we embarked on our second, the Jubilee Line, celebrating the new extension to East London. And so it went from there.
We've now done almost all of the shorter lines, but we hope to have a go at the first of the longer lines soon. Note the Bakerloo Line page only lists the pubs as we've haven't written a full report yet.
