It depends on the person. Homemade curry and naan is a good option. I make a hell of a baked ziti. But also if you make pizza with dough from scratch basically everyone is always happy and impressed.

Before I married someone who doesn't like seafood I used linguine in clam sauce as my flirtatious dinner for early dates. Delicious, leaves enough wine for two to have few inhibitions, but still be present, feels fancier than it is, and it's innuendo.
