I wonder if it's not a mistake to publicize this place, which is already pretty popular. Still, I appreciate it when others on this board steer me to a really good deal.
Il Granaio in Concordville is one of the best around here. Just plain good Italian pastas, salads, and traditional dishes, including excellent fish. I don't know how long it's been open, but it was packed on Friday night. The service was friendly and professional; they'll even banter with you in Italian, even if your Italian is pretty awful. And that's the point of this place, these are real Italians; they're not third- or fourth-generation, and neither is the food. The pastas alone could keep me going for my next ten visits.
Believe me, they don't waste a lot of money on decor, just wooden tables in a converted house (possibly once a professional office), but that suits me fine. It results in a great meal for a modest tab. You don't come here for a big occasion, just for a really good meal.
I didn't detect any regional emphasis. The fish I got was Livornese, but I wouldn't draw a conclusion from that.
