The Stinking Rose is a good choice. Expect to come away virtually sweating garlic.
But tastes and values differ. It really depends on what sort of thing impresses her. Fancy doesn't always equal good. Good isn't always fancy. The Taiwan Restaurant for instance is very authentic and very good, but small and unimpressive.
My advice is to take her to a place that impresses you, and at which you are most likely to be comfortable and yourself.
