My experience at Sizzler was that the “steak” was a half pound of gristle and barely edible. If they come back I hope they have improved quality.
People went to the Sizzler for their salad/taco/desert bar.
From what I read before they declined, they lowered the quality of the food and hoped people would not notice...they did, including you.
There were a lot of them around where I was as a kid and had those iconic TV and radio commercials with the sound of the sizzle and the woman saying “sizz-ler” in a whispered voice...but I don’t recall ever eating there.
