A few pubs in ED show Six nations games and internationals, but otherwise the answer is no. The Magdala used to show Heineken cup games on Saturdays (and was also the best location to watch internationals), but football always took precedence on Sundays. However, the new owners have removed all screens (and generally feminised the place) so a subscription to Sky or joining a local rugby club are your best bets. Kings College Hospital RFC is based in Dulwich Village.
