The Smithsonian combines a certain amount of simple charm with an elegance of though that is hard to explain in words. I will say this: Never have I ever eaten a tastier burger. It's got the sorta greasy flavor of a small, diner-ish affair, but is large-and-in-charge, for real.
This is one of the only restaurants in the small town of Hatfield. It is right of I-91 and a mile off route 5. They have a wide selection of regular lunch & dinners and many daily specials. The price is moderate and the food home cooked. It's popular with locals and worth a try.
