The words “deliver” and “sushi” should never be used in the same sentence. Sushi and sashimi (or any raw protein, for that matter) are much too prone to food-borne pathogens and temperature-related spoilage to be subjected to that no man's land in some guy's Toyota between the restaurant and your home.
Imagine a plate of sushi sitting on Rt. 1 in the middle of July in traffic. And sitting. And sitting.
Sushi needs to be delivered from a sushi bar within sight of your table in a restaurant. And even then, that sushi bar must be spotless, and manned (or womaned) only by experts.
