If you’re in London I’d thoroughly recommend a drink in the Jamaica Wine House - it’s a pub in the square mile that used to be a coffee house from 1652. It’s an amazing place to see - you can really feel the age and history of the place. https://londonspubswherehistoryreallyhappened.wordpress.com/...
