The service. Being in the industry I can't look past how bad the service was when the place was nearly empty at 1AM. The lounge server forgot our third round of drinks and we had to go up to the bartender to order through him.
The food was pretty basic bar food with a lot of different menu choices that were "Italian." Not sure I would make it a point to come back again unless it was just for their yummy gin elderflower cocktail.
