We ended up here last night. It's a tiny place with some of the worst service staff I've ever come across. The bartender decided to ask us what we wanted to drink about 10-15 minutes after we sat down. Note, there were only a couple of other people in the place. We had to flag her down to get a second round, and again to get the check. Since she ignored us when we were trying to ask for the check, my friend walked up to the bar, asked for the check and asked her NOT to run the credit card she was holding. She proceeded to run it anyway and then handed him the receipt. When we pointed out her error, she said the transaction wouldn't go through until we signed the receipt. At that exact moment, my friend received a text message stating that the transaction had gone through. After rolling her eyes a few times, she called up a manager, who said he couldn't reverse the transaction because it was up to the bank. Not wanting to cause a scene, we decided to work out the bill between ourselves, but we did not leave a tip... simply because that was an awful experience. This was the second time in my life I have ever not left a tip. Usually there's always something positive about the experience that guilts me into leaving something. There is nothing positive I can say about this place. The awful staff, the overpriced drinks (double the price of whisky elsewhere), the pretentious 'reserved' cards that they put down on every table around 7pm. It's a tiny space on the 33rd floor of the W, with a decent view but nothing is worth that experience. To make matters worse, today my friend checked his account to realize that they added a 20% tip to the receipt after we left. He will be calling the hotel tomorrow to register his complaint and I will continue to update after the issue is settled. Don't bother going here. We would have had a better night drinking water at home.
