This is probably the only activity you can do on Wall Street (minus taking photos of course). The entry fee is reasonable at $10 (cheaper if you're a student like myself). I wouldn't say this museum was breathtaking or large but it is very educational and I feel like it covered everything you'd learn in a Finance 101 course at university. Part of the museum are interactive with a section where you actually get to try making investing decisions and make money. There are many exhibits that are exhibits that teach you a lot. Since you can no longer go into the New York Stock Exchange I'd say watching the videos in this place is the closest you get.
Overall this place is worth a visit if you're in Wall Street and are looking for something to do. I also think kids (or eve adults) interested in Finance would enjoy the learning experience. However, I probably wouldn't rate this attraction highly enough to say that you have to come see it.
