Sister Marie Alice LaGrace claims the secret to a long life is loving God, one another and Denny's. For her 100th birthday, there's no other place the nun wanted to be than her favorite restaurant. Every day, Sister Marie Alice LaGrace eats the same meal at Denny's right after church. She always sits in the same seat, which the restaurant has now dedicated to her.
