We did the ONE Dine and Observatory combination. We went into Freedom Tower about two hours before our ONE Dine reservation. We had time to check in thru security, get our dinner tickets, go up in the elevator, which was awesome by the way, and go thru the observatory at a leisurely pace before time of dinner reservations. The hostess was very friendly and informative. The waitress, Stephanie, was very attentive, friendly, and funny. The food was fabulous. The views were breathtaking. Watching the city change from daylight to night time was awesome. Highly recommended!!
