Overpriced, just okay pasta.
I ordered the Mafalde Bolognese and I was quite disappointed... not only was the portion size smaller than the average, but it also just tasted like carbs. Of course, pasta is carbs, but good pasta has well-crafted noodles with a texture that doesn't feel like I'm just munching of boiled pieces of dough. The pasta sauce wasn't outstanding either.
On the bright note, my friend ordered the flatbread, which looked good.
The only redeeming factor for me was that Sienna has a nice, upscale ambience. But, I think that there are better options in Pittsburgh.
