Yes, the coupons are "Dine In" only. We used one at the Apopka-Vineland location last Friday night. Our pizza was very good.
I will say, for all of the Chicagoans who love Giordano's, the pizza they make in FL is not quite the same as what we are used to at home...But, it was still very yummy and I loved saving $25 on dinner.
