Sustainable seafood dinner at Ammo

Paul Greenberg, author of “Four Fish,” will hold a book signing and dinner at Ammo on Aug. 8. The Sunday night meal will feature four courses of sustainable seafood: oysters on the half shell; kampachi with avocado, chile and lime; oven-roasted mussels and clams with shell beans and fennel; and a choice of smoked arctic char with lemon cucumber and tomato salad, or grilled barramundi with caponata. Dessert will be roasted figs with honey ice cream. The meal will be $50, and books will be available for signing.
