I got an 8 oz filet Oscar and so did my wife. It was less than $100 but I'm not sure it was amazing. It was very good though.
BTW, I've lived in AZ my whole life and never went to The Stockyards. If you live in AZ, you should check it out. A cool historical place. Not quite Monti's historical, but still a cool place.
Also, the pecan pie was amazing.
