Chelsea Gregoire is something of a vagabond bartender with a talent for mixology. Her powers behind the bar led her to run for the Vice Presidency of The United States Bartenders Guild, which she lost by one vote. Her chemist-like attention to detail when it comes to cocktails has made her a favorite whether at Idle Hour or Pen & Quill. An active member of the city’s tight-knit bartender community for the past five years, she’s organized local bartender competitions and recently started the business Drinkable Genius, which guides new owners through the maze of opening up a bar. If you drop by any of the bars where she works, ask for an Old Fashioned. It’s her favorite cocktail, and her take on it will be one of yours, too.
