The marinated beets at Dario look like a modern sculpture, with thin sheets of the brilliant red-purple root vegetable balanced on a bed of sauce gribiche and garnished with delicate waffle-cut potato chips. Taste-wise, the tangy beets belong at the world’s fanciest picnic. The  hard-boiled egg, mustard, and fresh herb notes of the sauce gribiche evoke an elevated egg salad, and the dainty potato chips have a bold dill pickle flavor.
