I've never had British food, but for some reason I've always thought I would like it. Not to mention my strong fondness for Guinness. I really need to get out there and see.
seeing as guiness is an irish stout it is a bit out of place in english things to try and like list (cant abide it myself nor larger)
try some real ale or cider (preferably the scrumpy sort) if you do come over they wash the full english down 'reet nice like'
