Serendipity is best known for its HUGE mouth topping desserts. I've been there 3 times myself with guests from out of town. They love the place and dessert. I would definetly recommend their signature Frozen Hot Chocolate and Banana Float Sundae. The price may seem kind of hefty but considering the portion you get its well worth it. As for the food it's not the best I've had but decent. I would just go straight for the dessert!
The downside as others have mentioned is the long wait and crowds. Be prepared to wait at least 1 to 2 hours. Even with reservation there usually is a wait.
