With all the convenience stores and bakeries coming up with their own variations on the famous Cronut from New York, there are too many to choose from, but the Croissant Donuts from the Heart Bread Antique stand outside of Seibu Shibuya department store in Tokyo, and indeed the chain's other branches nationwide, are worth trying. Each Croissant Donut is made with layers of crunchy pastry that you can peel away and is topped with green tea, strawberry, chocolate or lemon frosting. And they're a bargain, too: only ¥280 a piece. 21-1 Udagawa-cho, Shibuya-ku, Tokyo; www.heart-bread.com.
