This restaurant is okay for a hotel restaurant. I was meeting a friend from out of town at the Hyatt so we just met at Annona for lunch. I didn't have high expectations for it since most hotel restaurants are just okay.
The location is conveniently located in Yorkville, I can't speak to parking because I took a cab but I assume its like any other hotel - expensive but convenient.
Our waitress was lovely. She was super friendly and helpful and was always there the moment you needed another drink or to top off your water.
I ordered the salmon and it was fine. It was a little dry and not as rare as I would like but it was not bad.
The cake I ordered was perfect. It was a rich chocolate cake that was somehow also very light and satisfying. It was so good I wanted another one :)
Overall, ambience was nice, location was convenient and food was good. I probably wouldn't come here again unless I was meeting another guest at the hotel though as there are many other great restaurants in the Yorkville area.
