Zakura is the latest name of the longtime Japanese restaurant in Amagansett, which some people still think of as Mount Fuji. It has a full bar with such drinks as a lychee martini. Inexpensive lunch specials — 12 pieces of sashimi over rice for $12 or a Bento Box for 41 5, for example — are poplar. The sushi bar is a long one, and there are 30 different hand rolls. The Zakura combines lobster tempura, asparagus, and lettuce topped with spicy salmon.
