Eataly

The lovechild of Mario Batali, Joe and Lydia Bastianich. This market/store/restaurant/cafe space is massive, and has to be seen to be believed. You could pop in for an espresso and a gelato, buy fish/meat/pasta to prepare at home, or even sit down at one of the many cafes and have lunch or dinner. If you love Italian food, this is your Valhalla.
