I honestly don t recall when I was so humiliated in front of my guest.
We made a reservation for 4 persons.
On arrival we got seated at a nice table with a view and received our menus.
In a moment a water comes to inform us that there has been a mistake and we need to switch tables to a table in the back. On our dissatisfaction about the situation we get a very rude response from the staff. Eventually we change the table to a smaller but also with a nice view.
A young couple gets seated at our original table.
Regarding the service, the food was served cold and separate - two main dishes and in 15 min the other two.
The appetizer 20min after we finished out main cores.
