Buy one dinner at Olive Garden for $12.95 and get another dinner FREE. The first dinner is an eat-in, the second is a take-out. So you can eat out today and stay in tomorrow. Choose among five entrees, lasagna rollatini with four cheese sauce. There’s nothing on the Olive Garden website I could find that says how long this BOGO dinner offer will last, so best to take advantage of this meal deal sooner than later.
