This is our favorite restaurant on Cape Cod.  The Sagamore Inn is a family restaurant with delicious homemade Italian dishes, Seafood dishes and American style dishes.  We ate there 3 nights and we each had Veal Parmesan with spaghetti and meat sauce, Shirley’s Famous Pot Roast (with real mash potatoes, as good as we have ever had in a restaurant) and Broiled Seafood Platter (scrod, scallops, lobster and shrimp sauteed in white wine & butter sauce.  All were marvelous!

We have no connection to the restaurant, other than loving to eat there. :)
