Whats a good romantic dinner idea?

Specifically, the meal. I have the rest figured out.

Stir fry is not an option. But it has to be something that can be prepared in 3 hours at the extreme most, for a somewhat low price. It also needs to be able to be easily kept at serving temperature for up to an hour, or easily brought back to it (oven and fridge available).

Suggestions? Recipe’s appreciated.
