Add all ingredients into a shaker with ice and shake vigorously. Strain into a martini glass and serve. To enhance appearance, drizzle chocolate syrup into glass before pouring martini. Note: do not substitute creme de cocoa or any other chocolate flavored liquor for the Godiva liquors, as they are the key to the drink and well-worth the added expense. After this chocolate martini, cheap imitations made with creme de cocoa are unacceptable.
