I ordered the porchetta at Osteria and was presented a wonderful plate of food. Even if the price wasn't so low, this is something to really look forward to. Perhaps a bit of a misnomer, my porchetta was four ribs served over polenta with canellini ladled on top. All in a light tomato sauce. The pork had a gorgeous aroma of fresh herbs. $10.
Another good call is the vitello tonnato appetizer.
