If there’s one thing SONIC Drive-In knows what to do, it’s how to make delicious milkshakes. The latest variety is bound to give you an extra boost, because it’s all about espresso. So while it appears that it’s not out quite yet, you might get lucky and be able to order one early. As detailed on the poster, SONIC has a new Espresso Classic Shake and Oreo Espresso Master Shake. We’re guessing the first one consist of vanilla ice cream and espresso, and topped with whipped cream and a maraschino cherry.
