I think there's a seam between discovery and ordering. If I am traveling on business, and I don't know what's in the area, then a unified interface is valuable.

I think there's a seam between discovery and ordering. If I am traveling on business, and I don't know what's in the area, then a unified interface is valuable. But if I know which restaurant I want, then the unified ordering apps are charging restaurants for a service (discovery) that the restaurant doesn't need any more. Seems crummy.
