Cotti Coffee recently started opening branches in Toronto. Cotti was started by some Luckin execs who had some disagreements over the direction of the company.Once watched a documentary on them. Dun know how accurate. But says their biz model is based on huge number of takeaway delivery orders to office based customers that the coffee is not bad quality and more reasonably priced.
Also how they thrived is introducing way more new experimental drinks to tempt customers. Some became runaway hits and made alot of profit for them. Quite different overall from Starbucks model. Saw many YouTube videos of star bucks flagship store in shanghai where they process their own coffee beans there and I thought it was ridiculous but apparently it attracts plenty of tourists
Their operation is similar to what you described. Mostly takeaway business. They have online ordering as well. The price is about 30% less than Starbucks which is attracting customers.
