Unlike some of the more common Japanese eateries, Rakuen serves authentic Okinawan cuisine. Start with the umi-budo—an interesting variety of sea kelp shaped like bunches of grapes (the bubble-like appearance has also won it its “green caviar” nickname). Other regional specialties include the homemade peanut tofu, which, despite the name, is not a tofu dish but a gelatinized mixture of peanuts that has a chewy but firm texture and discerning nutty flavor,
which is drawn out by a drizzling of soy sauce. Okinawan ingredients—such as bitter gourd and squid-ink noodles—are found throughout the menu, and the melt-in-the-mouth grilled ox tongue is a definite must-order.
