Opposite Thornton Heath Railway Station there is a Wetherspoon pub, called the 'The Flora Sandes' which is popular with both home and away supporters. Also close by is 'The Railway Telegraph' on Brigstock (as you come out of Thornton Heath station turn right and the pub is further down on the left). This pub serves Youngs beers and is quite spacious. It is then about a 15 minute walk from here to the ground (as you come out of the pubs turn right and follow the other fans). There are plenty of Kebab & Chip shops available on the route to the ground.
Otherwise near Norwood Junction Railway Station on the High Street is another Wetherspoon outlet called 'The William Stanley' (From the Station turn right at the Clock Tower into the High Street). The nearby 'Ship' pub on the High Street has also been recommended to me. Generally beer and lager are served inside the ground. Please note though that for certain high profile games, the Club choose not to serve alcohol to away supporters.
