Going to Houston's either on Scottsdale or on Camelback is like throwing dice. Sometimes its good and sometimes its not at all. Over the years and I have been eating there for years the staff has become less and less polished. I've watched it go from slacks to jeans and very attractive staff to just ok.
It's not cheap to eat there and you expect the food to be consistent but it always isn't. My wife loves the fall vegetable plate but the last two times it was not good the fish that I ordered was very overcooked. I sent it back and the wait staff rolled her eyes.
One other time (years ago) I was waiting with my wife and another couple and we waiting for 30 mins which was normal and person came in with his friends and handed the front person 100.00 it looked like and they were seated right away. I asked the wait girl how much she made a week and she looked shocked that I caught her. She said excuse me walked away I didn't see her for the rest of the night another person seated us 10 mins after that. I wrote a letter to the corp office and never got a letter back.
The real money they make is made off the snowbirds that come in for the winter. So during the winter I would avoid this place.
Good Luck.
