More than just burgers.
You can get far, far more than burgers and fires over here if you stay away from the Big Name Fast Food Chains, including lots of different regional specialities, such as chili, two different styles of clam chowder and the many different kinds of barbecue. All you have to do is have an open mind (and empty stomach) and ask the locals where they like to eat. Or, you can allow yourself to be blinkered by your prejudices if that's what you prefer.
