We tried the country's first 100% vegetarian drive-thru to see if it's better than the Chick-fil-A across the street - here's the verdict

There's no rule that says fast food has to make you feel terrible.

In recent years, American consumers have shown a craving for healthier fast food. Restaurant chains that offer low-calorie meals - that remain convenient and affordable - have sprouted across the US, forcing legacy brands like Taco Bell and McDonald's to rethink their menus.

The fast-food revolution is no more apparent than in Rohnert Park, California, where a Chick-fil-A sits across the street from up-and-coming vegetarian fast-food chain Amy's Drive Thru. On a visit to both restaurants, we found Amy's buzzing with diners long after the lunch hour.

We tried sandwiches from both Amy's and Chick-fil-A. Here's what we liked better.
