Very bad experience, no free entrance for hotel guests, the employees didn't even know the exact costs we had to pay.
There is one free drink included, but no you can only choose from 3-4 low price options.
The bar and the tables aren't cleaned frequently.
The staff in-charge is very unfriendly and doesn't like working.
One third of the small open-air area is not accessable due to reservation.
This is a very bad choice for a rooftop experience
