The name of this plant-based restaurant refers to both mushroom and mollusk. The latter is the only animal served, a nod to the environmental benefits of oyster farming: as it purifies water, promotes biodiversity and curbs erosion and coastal flooding. The sustainable ethos rules on the wine list as well, with producers that practice responsible farming, low-intervention winemaking and fair labor practices. Meticulously sourced vegetables shine here, like whole roasted lion’s mane mushrooms with black garlic and pickles, or corn soup with filet beans in a Virginia peanut broth.
