Red Robin Gourmet Burgers is rolling out premium-price burgers it has been testing for the past year. The rollout, under a new banner called "Finest line," starts with Finest Smoke & Pepper Signature Burger. It's a half-pound Black Angus beef patty seasoned with alderwood-smoked sea salt between a pair of buttered, toasted ciabatta buns serve as bookends. The chain said the burgers would be menu priced from $12.99 to $14.29. Most burgers on its standard menu are priced from about $9 to $10.50.
