Harry Caray's in Rosemont is good. Not as atmospheric as downtown, but the food's the same. It's a check-tablecloth Italian steakhouse; not exactly romantic, but excellent steaks and chicken Vesuvio.
Maria's is a pleasant Mexican place tucked away in an industrial strip. The food is well made, though not out of the ordinary (spicy salsa, big margaritas, good standards like enchiladas de mole, excellent flan) and it's a bit atmospheric. On weekends, there is often a guitarist.
The Sofitel O'Hare has a very nice French restaurant called Le Cafe de Paris, where you can get a romantic dinner, and a decent bistro called Chez Colette. The Sunday brunch is worth checking out, too.
