Forget what you think you know about risotto. Da Fiore's seafood risotto will blow you away. Made in the traditional Venetian creamy style, Da Fiore's risotto is so delicate and tasty, you'll be dreaming about it every time you see risotto on a menu. Only don't order the other's! Their's will not live up to this masterpiece. Oh, and the other stuff is good too.
The dining room is softly lit, elegant, but not uncomfortably romantic.

If you are adventurous, have the waiter design a dinner for you based on his suggestions.
