Perhaps James Slater’s most obvious asset is his warmth. He greets his customers at Knife with a crescent moon smile, so bright it lights up the entire room. And even though we’ve just met, he welcomes me with a bear hug that instantly disarms. Next in line is his creativity. Manifestations of Slater’s brilliance are everywhere: in his crowd-pleasing Green Bloody Mary, and in the apple foam that marks the top of his mimosas. Imagination highlights everything he does. And when it comes to cocktails, Slater doesn’t mind getting deep.
