One of my favorites of their iced treats! Only at this location. Named after John Arbuckle who roasted 25 million lbs. of coffee a month in 1907 on the Brooklyn waterfront!. This recipe uses Stumptown coffee. Very flavorful. My only complaint is that lately there’s a bit of a gooey consistency as opposed to the creamy consistency at the beginning of last season. Then it was perfection! Note: as if 2019, it was discontinued.😞
