We dined at Nine on Nine on a recent trip to Pittsburgh. We appreciated that the hostess was accomodating- our table was originally near the door and when we requested to be moved it was no problem.
Our waitress, while overall pretty good, was very slow in coming to the table to greet us and take drink orders. I ordered a cosmo and it was made Perfectly- I only wish the glass had been filled instead of the short pour I got.
The food is very good. I had the special lamb chops and, while a little more fatty than I prefer, were tasty and cooked to my specifications.
