Something quite magical - something Midnight in Paris-esque - happens when you enter the world of Sr Duncan. Ring the bell on the unsigned door, then glide up the staircase to an art nouveau mansion replete with high ceilings, stained-glass windows and sheet music laminated to the bar. Swing jazz could be playing over the speakers, someone might be tinkling on the grand piano or a couple might be doing the tango on a dancefloor as smooth as a porteño's pick-up lines. You might think you've been transported to another era, especially when you see the food and drink prices, which are a pre-inflationary steal. As well as being a sure-fire bet for a night of beer-fuelled fun, Sr Duncan functions as a cultural centre, hosting live music, theatre and dance classes; stay in the loop via their Facebook page.
