Some info about Twickenham pubs from another forum
"Cabbage Patch", out the train station do a left, can't miss it as it's on the corner on the way down (bear in mind your going away from the stadium going to the pubs) quite nice. I'd imagine it would be amazingly busy as it's first pub you hit from station and is always busy for Rugby Matches / concerts etc.
"Rugby Tavern", your traditional grotty working mans pub, which I quite like right across from the Patch, again will be busy but not as much. Quite small and cramped inside.
Personally if it's a nice day, I'd head for the river as it's only another 5 / 10 mins down the road. follow road your on round until you see Macdonalds, go down side street next to it, and turn left before you get wet, and you get to the "Barmy Arms", nice beer garden at front, or follow river along for nicest pub in area I reckon, the "White Swan", right by the river. No need to go into pub as everyone congregates outside as it's right on river with it's own beer garden, and beachy bit.
i'm lookin for a hotel as well ruffian
