1.) The ability to deliver from any restaurant, not just those participating or offering their own delivery service. 2.) Drivers in a large number of locations, likely closer to the intended restaurant than any "pick it up for you and deliver" service could ever be.

As a driver, I'm sure you make more money delivering passengers than burgers. Which would you rather pick: taking a ride across town and making $25, or delivering a $8 sandwich the same distance and making $5, tops?

Wait, did I miss the part where they can deliver from "any restaurant"? How would that work? Is that what their goal is?

This is basically Postmates.

I agree, but I guess the argument is they are more efficient because unlike Postmates their drivers can work as both taxis and delivery vehicles so will have less down time.

There is a big difference between - delivering food you have in your trunk in under 10 minutes, and what Postmates or Caviar does. It seems UberFresh is closer to a Sprig/Spoonrocket model than a Postmates model.
