I haven't tried Sprig yet, but Munchery's business model is awesome. They are not trying to be a fast / cheap food service. They hire top notch chefs who prepare high end food. The cost of meal is b/w $10-$15. The quality of the food is what you will expect in a high end restaurant. They are basically getting rid of all the real-estate of a high end restaurant and delivering awesome food directly to you (lots of economies of scale). I am spending roughly about $500 per month ordering food from them. Highest quality food, delivered to you at very reasonable prices (I'm pretty sure I'll pay at least 50+% more for the same food if I went to a high end restaurant).
