So what this POS company is doing that’s kind of interesting is they have a mobile app just like Uber Eats/Doordash but it seems to be direct through the restaurant: https://apps.apple.com/us/app/local-by-toast/id1362180579
Actually when I ordered through it I paid $45 instead of $60 via DoorDash/Uber Eats but the order was delivered by Uber.
The reason why I think this version will work is because it’s the same level of convenience in a centralized mobile app so single payment method, single portal to browse restaurants etc.
(I have no association with this company I just was looking into this last week on the train)
