Just a quick data point from my DS, who was just there.
Said he went with two friends as guests on his PP. Their total bill was 278. They had a bottle of Cava, a martini, and some fruity looking drink (not sure if they had any food or not -- pic didn't look like it).
He said the waiter made a "formalistic exception" in that the champagne cost 115NIS/bottle and the waiter initially said the limit was 100NIS per person, not 300NIS for the 3 of them. Eventually the waiter relented and my son said they had a fun time.
I asked if he tipped and he said yes, in cash. He didn't tell me how much.
(He also said that he got two other friends into the Dan Lounge and left them there, whilst he went back to Schmoozy with two other friends. To a limited extent, the avid use of the PP soothes the pain of the Amex/Staples clawbacks.)
