The user will be able to filter cafes based off current proximity, budget constraints, cafe reviews collated from food review sites such as Yelp/Burpple/Grubhub. A filter for pet-friendly cafes would be available too, allowing you to enjoy a tasty weekend treat with your favourite furry friend.
You'd also be able to pre-order your waffle and once you are within a certain radius of the store, sending a ping to the cafe prompts the preparation your order. This allows you to arrive in time for the perfect waffle consistency without the hassle of waiting. Collaborations & tie-ins with cafes could also promote loyalty stamps for extra perks.
