The Empire State Building is well-known around the world and I had the chance to discover why.
As soon as you see it, you recognise it: it might not be the tallest but it is still the most impressive in Manhattan.
But don't be impatient, since you will have to go through big queues (calculate at least 30min to an hour)
The ticket is pretty expensive (40USD the regular entrance, without professional pic in the photo call or activities or guide).
Once you have made it to the queues, you are taken to an elevator with a screen in the top that displays a video to entertain you during the 20-30 seconds that it will take you to make it to the top.
Then, you will be taken to the first stop. I can't remember which floor is it but it already has great views of the city.
As soon as you are done, another elevator and you arrive to the top of the building.
The views are stunning (not recommended for people that are not comfortable with heights), especially in a sunny day. You get to see all Manhattan, the statue of liberty in the distance, New Jersey...
It is a great experience that has to be lived at least once.
