For 98-year-old veteran Ross, Denny’s has been a familiar stop for many years. For his neighbor Sevastian, it was his first visit. Together, they shared breakfast, good conversation, and a reminder that sometimes the best moments happen around the table. ❤️
This Veterans Day, we’re honored to celebrate Ross and all the brave men and women who have served. Thank you for your service and sacrifice. 🇺🇸
