Olive Garden has been getting aggressive with the coupons. In addition to the Unlimited Soup, Salad and Breadsticks for $5 (lunch hours only), you can also buy a select lunch or dinner entrée for $12.99 and get a second entrée for take-out for free.
Keep in mind, the sit-down entrée includes unlimited soup or salad and breadsticks; they can be added to the take-out meal for an additional fee.
