The Toronto Blue Jays hit a grand slam last night in Game 1 of the World Series, which means all Denny's Rewards Members will score a free original Grand Slam at participating Denny's locations on Nov 3-10, 2025.
It's worth noting that many Denny's still give a Grand Slam birthday freebie as well. This isn't true everywhere, since Denny's is a franchise and not all owners run this promo. But the nearest locations to both me in NY and my brother in SC still send us a free breakfast offer each year on our birthdays.
