Bar Swift, AKA Swift's, is one bar with two floors. And it demands two visits. On the first visit, oysters and apertivos for Happy Hour upstairs. On your second sojourn, possibly much later in the same evening, a mug of the best Irish Coffee below.
If you can't make it to this Soho location, there are two other outposts (which we haven't visited) in Borough and Shoreditch.
