I don't know if Wally's (Rte. 236, S. Berwick, ME, 603-534-2030) is really the best since I've only been there twice and have no basis for comparison but it is pretty darn good. We went there last year on the way home and again this year. It is, quite literally, an open shack by the side of the road. I went a little overboard last year so really tried to keep spending in check this year. The girl who works the place (is she the same girl as last year?) is very sweet and helpful. We make our purchases and get back in the car just as 4 other cars pull in.
