I came to ArtBar thinking it would be a special dining experience. Instead, it seemed to be just another bar in a hotel. I couldn't even find anyone to check in with when I first got there. The bartender did not even know that they accepted Open Table reservations.
They were busy that night with a group from the hotel, so my order took a very long time. By the time my seared Tuna got to me, it was a little tough.
Overall the food was pretty good, so I did enjoy it, but it is important to know what to expect. It is not really a restaurant. Just know that you are going for a typical hotel bar food experience.
