My local Thai restaurant gets 90% of its profits from delivery, mostly Uber Eats. They have one tablet per delivery service in the kitchen. 
2/ Why not GrubHub, which is the market leader? Because GrubHub sucks, while they get business from it, it sucks down any profit they make. They'd rather make room on the counter for Amazon's delivery service, which while it produces little business, is profitable for them.
3/ Local bar also has Uber Eats. Why not GrubHub? "Because fuck GrubHub" they say.
4/ The Thai place shuts down their restaurant/delivery at 8:30pm, because it's family owned and they want to go home. Most of their business is lunch/dinners for companies doing large 200 unit orders, which don't happen after 8:30pm.
5/ Conversely, the bar doesn't get food delivery business until late at night, because they are one of the few businesses (other than Waffle House) whose kitchen is still open until 1am. It's a minor part of their business overall, but helps pay for the kitchen being open late.
6/ Uber/Lyft drivers also often do both services simultaneously, having one phone per service. This fascinates me how the gig economy has one device per gig, instead of apps all one one device.
7/ Uber Eats is the fastest growing delivery service, closing in on the market leader GrubHub. From talking to my local restaurants, it's because GrubHub treats them badly.

8/ These delivery services take ~30%, but they also save on a lot of costs (cloth napkin cleaning service, for example). One cost in particular is the dealing with credit cards: they just transfer money directly into the restaurant's bank account.
9/ As a cybersec pro, one thing I'm sensitive to is the overhead of credit cards; securing them is expensive. Having somebody take that off your hands is worth a lot. That the services hands everything for both customers and restaurant is important.
10/ GrubHub/DoorDash are explicitly restaurant delivey. UberEATS is an extension of drivers. PostMates in theory delivers other things, like alcohol, groceries, and laundry, but it's primary business till appears restaurants. Amazon's delivery is an extension of Amazon, naturally
11/ This fascinates me from a branding point of view. You have to choose what your brand means. GrubHub chose "restaurant delivery", whereas Uber targets the drivers with their brand, "come work for us". So different target markets in a weird way.
