This is somewhat of a different request. I'm looking for non-fusiony, traditional, yet delicious American fare. Something similar to a Cafe/Grill that serves delicious salads, burgers, sandwiches, but not some hole-in-the-wall. Price isn't an issue. I have picky parents coming into town, and aside from our upscale picks they want a tasty lunch or dinner not full of any esoteric ingredients many Boston restaurants like to serve. Any ideas? I'm looking for these places to be right in Boston/Cambridge. Thanks in advance!
