No not on the ESU concourse, but I think it is in the North Stand (have never been there myself so can't say for certain) so most from the ESU migrate there if they want to watch the 5:30 game.
We sit in the EU and always stay to clap the players off. We then stay until we get kicked off the concourse, having a coffee and using the facilities.
We then walk to the station to get the train to Lewes and normally we can get on the next one without queueing.
If it is a night game, or...
