You may not be able to drink whiskey at the office, but you can pretend you're Don Draper on vacation, sipping a Blue Hawaii at the Royal Hawaiian. That iconic hotel, featured in Mad Men's season premiere, is offering some classic cocktails—Blue Hawaii, Old Fashioned, Pina Colada and French 75—for just $3 for the month of April.

Fun trivia: The Blue Hawaii was actually invented in Hawaii, by Harry Yee at the Hilton Hawaiian Village. It's a mix of rum, pineapple juice, sweet-and-sour mix, and blue-as-Hawaii-waters Curacao.

As for the French 75, a drink of gin, Champagne, lemon and sugar, it was reportedly a favorite cocktail of King David Kalakaua.
