I recall that in their swansong issue, Gourmet magazine did a feature on the best roadside burgers. They described at seasonal Connecticut joint that server great hamburgers -- on white toast as they had for years. I think it was off the Merritt Parkway - but I could be hoping that was the case.
I'm light on details. ... Can anyone resurrect this memory or make a substitute recommendation for a trip North on the Merritt Parkway on Sunday afternoon?
