This hulking and well lit Gulf is right on Littleton and just off 495. Many a commercial vehicle or long haul driver can be found fueling up on gasoline and coffee at this station. A Dunkin' Donuts is attached, and both the Gulf and the gloriously familiar coffee shop are 24 hours. The bathrooms are clean and you don't need a key to get into them. The shop has plenty of cigarettes, snacks and lotto tickets as well.
