It was the last attraction of the day for us. We made a dinner reservation at the Summit Buffet and after that went up to observatory. When you make a reservation at the buffet or the restaurant, it will include your tickets to the observatory. The tower is great, we liked the elevator ride too. The restaurant I didn't like much - overcrowded so much, that it's difficult to come out of the elevator. Everybody is waiting for a table and inside the tables are too close to each other, waters are running between the tiny rows all the time. Food selection was ok, good enough. However, the view was amazing!!! We got some beautiful pictures!!!
