The most romantic foods would be foods you can feed eachother such as strawberries or any other berry. Maybe a nice pasta salad, and a bottle of your favorite wine.
Food you eat with your fingers that isn't sticky is always good, as are things on sticks that you dip. a mix of finger foods, and sweet and savoury dipping items would work.
The top romantic foods are strawberries,grapes,cherries and whip cream, some imported danish bleu cheese with crusty baguete bread or buttery crossants, red or white wine, and gourmet chocolates alway does the trick.
