Planning on taking your darling out for a bite of gold leaf prawns at the world's most expensive Valentine's dinner? Psh, that's child's play. Howabout a romantic night on a submarine while nibbling on strawberries dipped in chocolate?

For just $284,000 (oh, and that's the starting price), you and your lover can book a night aboard the Mile-Low Club -- a sleek submarine that takes couples on a journey into the blue at nearly 650 feet below sea level. Dreamed up by UK-based Oliver's Travels and launching this February 14th, the package includes a custom menu that features oysters, caviar and chocolate fondant with "essence of pomegranate." For a little extra, you can deck out the room in flower petals and enjoy a champagne breakfast in bed.

Patrons can choose the locations of the dive, while the  "aphrodisiac tasting menu" will  "ensure that guests are in the mood to make full use of the Lovers Deep facilities." Woof.
