dh is heading to Ireland next week with some people from his company (Guinness). They have some dinners planned out and we're trying to figure out what kind of clothes he'll need. They'll be in Kilkenny and Dublin, dinners are at Kilkenny Castle and The Lady Helen Dining Room at Mount Juliet in Kilkenny and the Mahaffy House in Dublin. Is anyone here familiar with these places? Would khakis and a sport coat be okay, is a tie necessary or recommended?
