A work-in-progress index of lounges, smoke-friendly hotel bars, and members’ rooms that reward going out of your way for them. We add to this slowly — one city at a time, after someone on staff has been.

Coming soon

• New York — four rooms below 34th Street that still keep cedar behind the glass
• London — the surviving cigar-friendly cellars from Mayfair to St James’s
• Madrid — an evening’s walk through the last great smoking cafés
• Havana — complicated, but unavoidable; the etiquette and the rooms that still matter

If you know of a room that belongs on this list, the editor would like to hear from you.
