Monsieur Zarse asked me to post details for all of those who have not had the pleasure of the 'Lamb and Flag'.
33, Rose Street, Covent Garden, London WC2E 9EB. Rose Street is a small cobbled lane linking Garrick Street ans Floral Street. There is also a small alley way linking through from Long Acre to Floral Street if coming down from Covent Garden tube. See attached map if you're still confused.
Closest tubes/train stations are Charing Cross, Covent Garden and Leicester Square. Can't advise on buses as I don't know how they work.
Rendezvous time is from 15.00
See y'all there.
