Was in Vegas for Memorial Weekend with friends and we decided to check out Serendipity before a friend of ours had to take off. My friend and I split a Frozen Hot Chocolate (the menu indicated this as one of their signature items), and I had a few bites of their Chili Cheese Hot Dog. Each was priced at around $10.
As much of a fan I am of the movie, I am not so much of the place. The Frozen Hot Chocolate was rather disappointing - it was basically a chocolate flavored slushee. The Chili Cheese Hot Dog, on the other hand, was so huge that it came in a box of it's own and was quite good. I don't know if it's worth $10, but then again it's Vegas...
