Dont make the food spicy or like chinese. stick with a simple italian meal. Steak gorgonzolla goes well with any palate. Make a very nice filet minot. Dont use babeque sause but use a meat baser like an A-1. That make fettichini alfreado and one or two clovers or garlic and pepper.
Italian food is romantic and and a great thing to cook together. Its a great meal and a great way to get the night started.
Finish up dependind on your taste with a fresh fruit custard or be cute and fun and bake a cake together. You'll both get messy and have fun
