The Jeffs are preparing for their most epic beer run yet, across the pond to the UK! To get ready, they sit down with Thomas Vosper, author of Historic Pub Crawls through London. Vosper shares his pub crawl history which has taken him to over 350 pubs throughout London. He also tells the Jeffs about some must-visit pubs not on the average tourist's list. From Big Ben to Sherlock Holmes, pub crawls in London offer a unique and rewarding way to view the city and learn its history.
