Seriously?
What is a drone-pickup? If you're talking about flying an unmanned quad-copter to the restaurant for them to strap a meal to it, the answer is no because it's probably illegal. You can't fly out of your line of sight and there's lots of trees, and you can't fly over people, and there's lots of people in the parking lot etc during meals.
That's an answer I cannot provide. Best to ask the restaurant directly.
