Luckin Coffee opened their third outlet within 300 metres of each other! (Why?) I succumbed to using their app about a year ago and users make their order there. Once the drinks are ready, the order page will update to QR code for you to scan to acknowledge collection of drinks. My favourite is the Iced Minty Chocolate Frappe without whip. You can't adjust sugar level so drink in moderation.
