The Jeckyll and Hyde Club offers an opportunity to enjoy a meal and watch a show at the same time. This restaurant is not your average dining experience. Instead as you are eating you may see some of the pictures on the walls surrounding you appear to change or move. No, it's not your mind playing tricks on you, it's part of the show for anyone dining there. Speaking of the show, there are also live actors in costume that will appear from time to time to "scare you". While it's not very scary, it's a unique activity for an 18-year-old in New York that she won't experience in most other restaurants.
If you want to show off your skateboarding skills, you can skate from eight in the morning until dusk each day for free at Hudson River Park.

Take a relaxing walk through the rock garden admiring the beauty of nature, or return to your childhood with a ride on the merry-go-round for just $2 per ride per person to finish off your date in the park.
There aren't many cities where you can go back in time and explore a castle, but New York City is one of them.

The castle offers breathtaking views from the top tower, allowing you to see much of the city. If you are thinking about proposing to your girlfriend or maybe just asking that someone special to be your girlfriend, this is a romantic opportunity. There is also a bird observatory at the castle to see and learn about various species of birds from the area.
