R Taco was acquired last year as part of Arby’s purchase of Buffalo Wild Wings. But the chain was hardly a throw-in. Despite activist pressure, BWW held onto the fast-casual taco chain, even as it sold its pizza concept, PizzaRev. Now, R Taco gives its parent, the newly created Inspire Brands, a growth concept. The chain, formerly known as Rusty Taco, offers a wide selection of tacos, including versions with fried chicken, achiote pork, fried fish, beef brisket and grilled vegetables, as well as all-day breakfast tacos.
