I don't expect to find a fresher dragon fruit than this one, so after a half-dozen samples at home and abroad, whole and juiced, I can say with assurance that only the bright spiky rind lives up to the name; the flavor is bland as can be.

Oc nhoi thit (25,000 dong), snails stuffed with their own meat and perhaps pork, too, were studded with whole peppercorns. After withdrawing the meat and wrapping it in a mint leaf (or two, for the especially big ones), I dipped them in a sweet-and-sour sauce laced with garlic.
