With Easter Stout on cask (I think), I'd say the Bull & Castle is the one to hit. Follow it with an O'Hara's IPA and take some bottled Brainblásta and Oyster stout away with you.
I don't think the Porterhouse does off sales, and if I were picking on I'd go for Central for Copperhead and Bruinette over Temple Bar's keg Easter Stout and Amber.
