I subscribe to the idea that a piece of perfectly presented fish is one of life’s great pleasures. Silken bluefin belly with a sprinkle of caviar; soft salmon draped over a sliver of torched rice; a slice of supple baby yellowtail, delicate but insistently flavorful. At Yama Tsuki, on Greenwich’s West Putnam Avenue, you’ll find all three. Family-owned, the business operates this restaurant alongside a wholesale seafood business and several restaurants in Long Island and Baltimore, personally sourcing very high-grade fish on twice-yearly scouting trips to places like Japan, Indonesia, the Faroe Islands, and New Zealand.
