This is an old thread, but we're here on MV right now and had the best lobster rolls i've ever tasted at MacPhail's Corner Cafe down on Dock Street in Edgartown. It's a new cafe, where Mrs. Miller's Muffins used to be a decade ago. Got a chance to meet the owner and found out he went to culinary school in NYC and comes with a lot of previous experience. We did breakfast there one morning.. amazing muffins and delicious bacon egg and cheese. The owner gets the lobster meat directly from the Net Result so it is hands down the best and freshest around. No fillers at all, just a little mayo on a toasted and buttered home-made ciabatta bun. You need to try it.
