One of the best-known restaurants on the island paradise of CapriCapri is Il Riccio, perched on a cliff on its northwest coast. The Bay of Naples tinges its terraces in shifting hues of soft browns and grays, turquoise, and indigo, as in the Grotta Azzurra, a hundred meters below, among the island’s most-visited places. The most original feature of Il Riccio is the “temptation chamber,” a refrigerated room, which enchants almost everyone who visits it, and which is accessed through an automatic door.
