For a Danny Meyer restaurant inside the Whitney Museum, Untitled comes across as surprisingly down to earth, with no pretensions. Friday through Sunday nights, the restaurant serves a three-course prix fixe, in which the first and last courses are shared by the table, and diners choose their own main courses. On my last visit, I had an amazing entree of ricotta gnocchi with Swiss chard and hen-of-the-woods mushrooms. I noted how fresh and (again) unpretentious — not over manipulated, but just letting the goodness of the produce speak for itself — each dish was, including the pickled goods that arrived with the bread, especially the pickled Swiss chard stems. This is such a happy edition to the neighborhood — a great place for a delightful and casual meal.
