Pubs in Oxford City Centre

[Challo]

Off into Oxford City centre on the 21st to catch the final 6 nations fixtures and a general booze-up. About 8 guys in today looking to get into Oxford around mid-day grab some food and then settle down in a few pubs to catch the games.

Any recommendations for a good place to grab food, and pubs to watch the rugby. Ideally in the city centre as we will be getting the train to and from.
