This month, you don't need to be at the end of a rainbow for an exciting surprise—just walk into Dunkin'. The chain recently announced the return of Irish Creme-flavored coffees and espresso drinks after a very long five years. According to a press release, the "smooth, velvety" Irish Creme flavor will be available to order as Dunkin' hot, iced, and frozen coffee, as well as the chain's espresso drinks.
