I don't have any suggestions as such but I would urge caution. Last time there were quite a few ugly scenes with people outside pubs threatening Albion supporters and a few glasses thrown - that was a evening kick off as well.
I was asked the score as we worked away from the ground after the game - luckily I can do a passable northern accent for a few words and remembered to look miserable and say "they won"
My friend at uni is a doorman back home in chesterfield and he works on the door or the pub nearest the ground. Says to avoid that like the plague. From what he says Brighton fans are best off going straight to the ground.
Couple of seasons ago (the Monday night) we went to a pub called The Chesterfield, about a five minute walk from the ground. Cheap beer, pool table and a quality chippy over the road. They let you bring the food in the pub as well. Highly recommended.
