At Olive Garden restaurants, buy two dinner entrées and get an appetizer or dessert for free via this printable coupon. That's the best freebie we've seen from Olive Garden since it offered a free kids' menu item with the purchase of an adult entrée last week (since expired). It's valid for dine-in orders only. Other exclusions apply and the deal ends May 27. Click here to find an Olive Garden location near you.
