A new drive-thru salad bar should scare legacy fast food brands

Fast food drive-thrus are attractive for four main reasons: the food's cheap, fast, delicious, and you never need to leave your car. A new chain is offering those four things plus one more: food that's healthy.

Called Salad and Go, it has six locations in Arizona and serves ... you guessed it. Its co-founder, Roushan Christofellis, hopes it will serve as an alternative to legacy fast food.

"We know that so many of those people eating from traditional drive-thru fast food are forced to go there, because they, just like me, needed something convenient and affordable, and that was their only option," she tells Business Insider.

Salad and Go sells 48-ounce salads, all priced between $5.74 and $8.23 depending on whether you add chicken, steak, or shrimp. It also offers soups, smoothies, and breakfast, which all cost around $4.

Its drive-thru model is what largely allows the chain to keep prices low, Christofellis says. Since the 650-square-foot locations don't have interior seating, Salad and Go has low operational costs, and as a result it can keep its salads under $6.

The chain plans to launch eight more Arizona locations by the end of 2017, and elsewhere in the US in the next two years.
