Hamachi and Ahi Tuna Crudo at Prospect in San Francisco. Really fresh hamachi (yellowtail) and tuna with grapefruit aguachile (a fancy word for a ceviche-like mix with lime juice), avocado, fried shallots, and puffed wild rice. First time at this restaurant and absolutely loved it! It will be in my regular San Fran rotation. Great menu, terrific food, nice vibe and ambiance, and outstanding service.
