15 East, Tocqueville’s long-planned sister restaurant, has made a lot of fans with its excellent sushi and sashimi. But owner Marco Moreira’s proudest achievement may be the “degustation of sea lettuces,” a $14 appetizer that presents New Yorkers with eleven varieties of authentic Japanese seaweed. “Seaweed is so unappreciated here,” he says. “You see seaweed salads that come in already dressed and frozen, with different seaweeds mixed together. I wanted to create a dish that showcases different seaweeds, textures, looks, and flavors.” As always, mouse over the different elements of the dish to see them described in Moreira’s own words.
