Remember this from last year?? We went and took the kids before school we had a blast! They gave us 7 free grand slams! Denny’s is offering a free Grand Slam February 9th from 6 a.m. – 2 p.m. No purchase is necessary, dine in only! They did this last year following the Superbowl and offered coupon books to dinners or rainchecks (because they were so overwhelmed with customers).
