We were in Pittsburgh for Carnegie Mellon parents weekend. Having failed to make dinner reservations, things were looking grim- every popular restaurant was booked all Saturday night. This is where Trip Advisor saved the day. Found highly rated Zinho, a Portugese restaurant with an award winning chef. And it had availability, which, along with the patrons (few parent/college kid groups) suggests this is local secret. Though close to Walnut Street shopping, A bit hard to find. Non-descript, even disappointing little building (I read once a service station). But decor, while a bit old world, charming. Family owned and the service was very attentive. Food was dynamite. My wife had Chilean sea bass special- very pleased. I had a very tasty liver, onion and bacon appetizer, and excellent duck dish (though a bit dry) in Grand Marnier sauce. My somewhat picky 13 year old raved about the salmon. Oh, almost forgot, the Portugese corn bread was Da Best! a bit pricey with Entreed $25-$30, but maybe that is Pittsburgh prices. We heartily recommend.
