Well, this was the DoubleTree Warsaw, a hotel that used to have a very good lounge with excellent evening food and drinks. They're selling all room types proudly advertising an Exec Lounge.
The Hilton Warsaw offers Diamond and Suite (Exec Rooms are pulled from sale) guests drinks and small snacks at the bar during the regular hours which means soft drinks during the day and the alcoholic drinks at night. The snack was served in a paper bag in boxes but the drinks were the same.
On Twitter, Hilton have confirmed that its hotel discretion to close the lounge and replace it with a voucher for one drink and one snack, meaning the brand standard really has changed for EMEA. They don't seem at all bothered the hotel is conning guests into booking Exec Rooms and Suites with no lounge available and no warning during the booking process.
