I had a chance to stop by Cliff Barnes a few years ago and it was fun to see! It was fairly early on a weekday, so not many people were there, but apparently it gets a good crowd on the weekends. (I actually chose Stockholm as a stop on a European trip from the US because I'd randomly run across the fact that there was a Cliff Barnes establishment there - maybe I googled 'Cliff Barnes' for some reason? ..not that one needs an excuse to visit Stockholm!) At the time (I think August 2015) there was a Sue Ellen bar/lounge a bit closer to the city center, and of course I dropped in for a nice stiff vodka drink! I'm not sure if that was the same as the current lunch place.
