For my mother's 50th birthday I would love to take her some place special. She loves Italian food and I just took her to Babbo for her 25th anniversary. So now I was thinking either Del Posto, Felidia, Gotham Bar and Grill to name a few. What is this best among these three? I have heard many mixed reviews on Del Posto. There really is not that much about Felidia. Seems like most people love Gotham Bar and Grill. I am open to other suggestions but keep in mind I only would be considering high end restaurants. Cost is no object-thank you everyone!
