Let it never be said that Earlsfield doesn't cater for rugby fans. Known for having a significant South African, Kiwi, and Aussie population, the local pubs welcome fans of all nations to watch matches on big screens.
If you're looking to watch the Six Nations matches, there are some great options in Earlsfield.
The Wandle is showing the matches and I hear rumours of a marquee as well. It doesn't look like they're taking bookings, but check with them directly.
The Halfway is also showing all the matches. They have match times listed on their events page.
The Leather Bottle is advertising the first round on them for table bookings of four or more people during Six Nations matches.
So get out there, support your team, and support a local pub too!
