This past month, Bethany’s Airport Diner started serving dinner on Mondays and Tuesdays, from 5 to 8:30 p.m., including dine-in and take-out orders. According to owner Bethany Coviello, this is the first time in 10 years the diner has offered dinner services. Open since 1993, the admired diner has offered breakfast and lunch, accompanied by the Block Island State Airport view.Coviello opened the restaurant when she was 27 years-old, and has now been running the diner for 28 years. “I loved Block Island and the opportunity fell into my lap.
