It is clear that you have a magnificent view of NYC from the One World Observatory (almost 400 m). However, you should be lucky that the weather plays along. So if you bought your ticket some time in advance, perhaps even in connection with a visit to the One Dine restaurant on the 102nd floor, you could be very disappointed if the view is not good due to bad weather. Nevertheless, it is highly recommended to buy your ticket in advance to avoid long waiting times at the ticket offices and elevators. In any case, we were able to go up immediately in one of the impressive "digitalized video screen elevators" and were almost alone in the elevator. When booking our restaurant visit online, we had to state whether it was a birthday, which was the case. And we were asked again at reception. But that was it. There were no consequences (e.g. a candle or a small cake). So we didn't understand the point of this question. The food in the restaurant was fine; However, we were not expecting fine dining at the highest level. The service was friendly and efficient, but we were a little disappointed with the ambience that evening. While we were dressed quite smartly, we saw several guests in shorts, short T-shirts and flip-flops or sandals, as if they had just come from the beach. Of course, the restaurant's owners are only interested in money, but as a guest, especially if you are dressed a little better, you would wish that in such a spectacular place you did not necessarily find the ambience of a fast-food restaurant. Although this is not to say anything against fast-food restaurants per se. Ultimately, the building lives from its height with the phenomenal view and is therefore worth a visit.
