Talk about tantalizing: For years, Sonic ran nonstop advertisements in our region showcasing its juicy burgers, luscious slushes, and tasty toaster sandwiches. But the fast-food chain didn’t operate any franchises in New York State, let alone the Hudson Valley. Then in May, Sonic opened a location in Kingston. The verdict? It was worth the wait. Not only is the guilty-pleasure grub scrumptious, but the restaurant’s setup allows customers to sit comfortably in their cars while a roller-skating server delivers their meal. It’s a scene straight out of Happy Days. And with a second location set to open in Wappingers Falls this fall (with whispers of even more spots to come), there will be plenty of happy days ahead for the Valley’s fast-food fans.
