Startup Idea : Takeout

A lot of Restaurants have deliveries but there are many that only do takeout (e.g. food trucks, small cafes, local small restaurants). The waiting time for these places can be very long so it would be useful to have a mobile app to order, pay and queue for your food/drinks. Companies like Starbucks already have their own app and this would serve as a middleman for visitors to see all restaurants. This is sort of a digital queue app but specifically focused on food services initially.
