All-day brasserie with art deco swagger serving proper food and cocktails in a converted Victorian railway building on the Quay.

You're walking into a proper grown-up space here—the kind of place that takes itself seriously without being a nightmare about it. Cosy Club occupies a listed Victorian building down on Mermaid Quay, all exposed brick, soaring ceilings and that slightly theatrical vibe that makes you feel like you've stepped into somewhere actually interesting rather than a corporate chain (even though it technically is). The menu hits that sweet spot between accessible and ambitious: think decent burgers and fish and chips alongside richer stuff like duck confit, all executed with actual care. The cocktail list is extensive without being pretentious, and they do a solid job with coffee during the day.
