Shepheards pie, (personal favorite)
corned beef and cabbage,
irish soda bread (not a fan)
good Irish cheeses, dubliner cheddar cheese comes to mind, and sausage or corned beef platter (like an appatizer)
bangers and mash basically sausage and mashed potatoes
irish colcannon (winter veggie cassarole)
Irish coffee always sounds like a good idea to me :-)
