If you are looking for a rather different dinner with your significant other, I recommend trying the Cable Car Sky Dining Menu. The whole trip lasts between 90 min to 2 hrs, i.e. three rounds between The Jewel Box Station and Sentosa Station.
For your convenience I post the current menu here:
"Soup/Appetizer/First Round Cream of Tomato Soup Served with Garlic Crostini
Smoked Salmon Salad With Mascarpone cheese
Main Course/Second Round Grilled Beef Tenderloin with Rosemary Jus Served with sauteed garden vegetables and potato wedges or Pan-fried fillet of Salmon with Honey Miso Served with sauteed garden vegetables and mashed potatoes
Dessert/Third Round Chocolate Brownie Served with chocolate sauce and strawberry coulis
*Inclusive of a glass of house wine for each diner"
Diamond Set - $ Protected content nett) Per Couple Availability : 13 Dec Protected content 08

With about Protected content per menu it doesn't come cheap, but, again, dining in the sky is something you won't do every day :).
