Aggregating many restaurateurs at a single kitchen, and encouraging families to order from that kitchen, a bundle of meals, could save significant money on delivery. And landlords could also offer their own delivery app, for more savings. For a restaurant brand owner, leaving that kitchen means leaving those bundles and customers. And replacing him(for many customers), is a possibility. That's one way landlords could gain some lock-in. Also, even without significant lock-in, landlords that may have many kitchens, could have significant purchasing power of food ingredients. Even if they earn only a single digit percentage on that, food ingredients have rapid turnover, so yearly ROIC is significant.
