So I've been wanting to eat at a Vetri restaurant for a long time, and I'm just about to break down and make reservations, but I'm not sure which one to choose. Although I love all kinds of great food, I don't like anything overly formal or stuffy. I'd like to keep the cost to around $50 pp, sans alcohol, but I'm willing to bend on that to get a true idea of what people like so much about him. Can anyone comment on the differences between the three restaurants? I had heard that Osteria was more informal?
