It’s not actually a castle. It’s a boat. A boat with layers of entertainment. There’s a comedy club and a night club in the bottom deck, to a chilled out lounge bar in the middle with couches and, on the top deck, a beautiful place to sit and have a drink on a summer evening, overlooking the Thames. The Tattershall Castle is smack in the middle of tourist territory along Embankment just right of Embankment underground station, so in the summer it can get crowded, but we’ve always had good times there. (Just watch out because the rocking of the boat makes you feel tipsy before you’ve even had a drink and makes you discount the number of drinks you have had once you start!) I popped in for a drink with a friend the other night and thought I’d take a few photos for you.
