The food is fantastic, but the service is not.
Had a salad and pasta with meatballs and it was all very delicious.
The service was terrible. The AC was dripping water on us at our table and the host refused to move us to a new table and expected us to just get water dripped on our heads and food all night. We insisted that we move to our server and eventually were moved to a large family style table with another family that we did not know...awkward.
Our server also semi-neglected us because she was trying to give speedy service to another table who had to catch a show at 7:30. Well, we were going to the same show and her focus on them and lack of attention to us made us late for the show.
Sienna needs to step up their customer service. They want to be an upscale restaurant, but they're providing diner-style service.
