I've been to Pittsburgh twice and on my recent visit decided to check out the Squirrel Hill area, I'd been by there on my last visit and it looked like a good place for good food. Just like NYC one of the biggest dilemas in Pittsburgh is deciding where to eat because there are so many good looking places.
Save yourself some time and arguing by taking my advice and come to the Murray Avenue Grill. The fish here is excellent, they use freshwater Atlantic Cod and give you a really big helping. Our waitress was extremely friendly and the dining atmosphere was nice. If I return to Pittsburgh which I hope to do because the city is absolutely amazing , I'll definetely be eating here
