Dinner in Downtown Pittsburgh On Mon 1/12
My favorite, without question is Nine on Nine on Penn Avenue. http://www.nineonnine.com/
If you are in the Marriott the Steelhead is a pretty good choice. If you are in the Marriott Courtyard, that hotel houses the Somoma Grill which is also a pretty good choice. Eleven is a very short cab ride (or kind of long walk), but very good. If you have a clear night make sure to go over to Station Square and take the incline up to Mt. Washington to enjoy the best city view in the country!
