Two years ago the Beach Plum became, briefly, the best restaurant on Martha's Vineyard. An old, dowdy, boring place was transformed, both physically and with a new chef, with some truly exciting food. Alas, he left and last year the place was awful. This year, another chef and, well, a work in progress but much progress is needed. The basics are sound: beautiful room, good service, outstanding ingredients (the tuna and the chicken must be some of the best on the Island). But the preparations were utterly incoherent. Nothing worked. And the prices, even by Island standards, are truly insane. We will not return and we would not recommend it unless the food improved and/or the prices dropped to the level of other, and currently much better, establishments both Up-Island and in Edgartown.
