Located at the fork in the road where Newtown Avenue and Chestnut Hill Road meet, this full-service gas station was bought three years ago by brothers John and Tom Giafardino. Since then, more than 70 percent of the business has come from repeat customers who rely on Cranbury Service for fuel and necessary maintenance and repairs on their cars and light trucks. A mechanic is generally on duty Monday through Friday from 8:30 am to 6pm and by appointment. Cranbury Service seems to have found a home in this wooded section of Norwalk.
