I love this place. Considering it is at the Wynn, it is very unpretentious and affordable, especially for a wine bar/tapas restaurant.
I am giving it 3 stars because I have been there twice now and both times the service has been horrible. Both times we have sat at our table for at least 10 minutes before anyone even approached us to offer a menu. Then, once we got the menu, we had to ask for the actual wine menu. I mean, you are a wine bar, that should be a given. Once we had our menus, it took at least another 15 minutes to place our order.
After this, the food is excellent. At one point, the Executive Chef actually delivered part of our order and to check on us.
Overall, I love this place and will definitely continue to go back. Hopefully they can work out the kinks with the service - it is not a big place and I can not imagine how the Servers would be overwhelmed with the small amount of tables they have at a time.
