if you just want to go up to the observation deck, no you just need to buy tickets, if you want to have a meal at the five sixty restaurant, then you have to make a reservation.
Reservations is very necessary. They always full because it is not that big enough to accommodate a lot of people. And don't forget your attire. Enjoy....
Only for the restaurant, not for the viewing platform
