Inside the country's first 100% vegetarian drive-thru restaurant

Fast food is a guilty pleasure many Americans find impossible to avoid. But Amy's Drive Thru is a first-of-its-kind restaurant serving up organic, local, vegetarian, and non-GMO fare - and they're doing it well. 

Amy's has been an established food brand for over 27 years, stocking sections of Whole Foods and other grocery stores.

"Over the years we felt we've been part of changing frozen food," Operations Director Paul Schiefer tells INSIDER. "And we had customers and partners saying 'Hey I wonder if you can do the same thing for fast food.'"

Their pioneer location opened in Rohnert Park, California in July 2015 - just an hour drive north of San Francisco. We decided to see for ourselves how the meatless fare stacks up to established fast food eateries.
