Although different variations of coffee cocktails pre-date the now-classic Irish coffee by at least 100 years, the original Irish coffee was invented and named by Joe Sheridan, a head chef in Foynes, County Limerick but originally from Castlederg, County Tyrone.
Tom Bergin's Tavern in Los Angeles,[REF] also claims to have been the originator and has had a large sign in place reading "House of Irish Coffee" since the early 1950s.
