The fun we would have here when it was the Camden Tup, and quite a pleasant pub. Football matches were watched and colleagues were post-work drunk with, girlfriends were encountered... I was even invited up to the crew quarters upstairs once. It was like the league of nations, in a kitchen / living room full of glass fronted pub fridges.
Now its the Black Heart, presumably a response to the numerous White Harts you see dotted around. I suspect the spelling and meaning hasn't even occurred to them.
It's very cool and very trendy, very dark and very loud. Very on the tourist trail. And very busy.
Camra discount on the ales. Which is nice. Not one I rush to though.
