Katie O'Brien's Irish Tavern Sheffield

You'll find yourself on Mappin Street in the heart of the city centre, pushing through the door of a place that feels like it's been pulling pints since before anyone cared about craft beer trends. Katie O'Brien's commits to the bit without being annoying about it—dark wood, actual Irish staff who know their stuff, and a crowd that ranges from after-work suits to proper regulars who've claimed their corner of the bar. The music's loud enough to add atmosphere but not so loud you can't hear your mate's terrible story, and there's usually something on the telly that matters to someone.
