romantic polish dinner
That's probably the first time in history that "romantic" and "Polish dinner" have ever appeared next to each other. Polish food is excellent comfort food, but there ain't a spark of romance in it. At it's best, it would remind her of her grandmother. Unless it's at it's best, it's bland and dull. You're better off trying your luck with a romantic dinner wherever you come from.
And no, I'm not knocking Polish food. I grew up on it and like it very much, and cook it well and often myself. It's just not something to impress a date with as a foreigner.
