UberEATS might consider implementing a feature called "Upgrades." This idea, which is quite popular in the gaming sector, could also be applied to a food delivery platform. For example, options like larger portion sizes, additional toppings, or extra side dishes could be offered as upgrades to the existing order, potentially at a modest discount compared to ordering them separately. As customers recognize the benefit of receiving more for just a little extra cost, they are likely to opt for these upgrades, thereby boosting the average order value. On the backend, an algorithm could be developed to recommend upgrades based on users' past orders and preferences, enhancing the personalization and effectiveness of this feature.
