For the longest time, the owners of Inn and Trail Gourmet called him “flat white guy” because they didn’t know his name. Steve would frequent the Glen Arbor business almost every day and order a flat white—an espresso coffee drink. Turns out that Steve Reddicliffe edited “The New York Times Essential Book of Cocktails”—a spirited tome of recipes, stories, and reflections written by quaffing legends. On Thursday, June 1, from 5-6:30 p.m., Steve will sign copies of the book at Inn and Trail while guests sample a couple special drinks he has created for the event.
