Love the direction these companies are taking. Food delivery as a whole tends to be unhealthy, expensive and takes a ton of time to get delivered.
Couple other options for those of you in SF/East Bay:
-Sprig (eatsprig.com)
-SpoonRocket
Personally, I haven't had SpoonRocket before, but I've loved Sprig's service and the food. Having Google's former Head Chef doesn't hurt :)
