Serendipity's Creme De La Creme Cheesecake

Serendipity is little restaurant in New York City, as featured in the movie Serendipity (with Kate Beckinsale and John Cusack). They are famous for their Frozen Hot Chocolate (Serendipity's Frozen Hot Chocolate With Real Whipped Cream), but this cheesecake is a part of their many other desserts. I haven't tried it yet, but if it's from Serendipity, it just has to be good!
