Ate at Mix a week ago. You really should go there to at least see the bar/restaruant/view. You really should go there for the wonderful, wonderful food. You should STAY AWAY if you value service, let alone good service.
Our waiter was so incompetent we were relieved when runners delivered our food. At least they made an effort to be polite, friendly and explain the (wonderful) food.
The "wine manager" (that's what he called himself) also provided great service. But our waiter was so incompetent and rude that at the end of the evening we spoke to the restaurant manager and left our tip for the wine manager with him rather than trust it to the waiter.
I have never had such terrible service and especially not in a restaurant where we spent over $500 (tasting menu/wine package). We were severely pissed off and would never return and would never recommend it.
But go for the view.
