Gosh! I have also heard that they add many stuff to rice especially during weddings , so that after eating few handfuls junta feels stuffed - Not sure upto what percent it's true
One of my close frens dad once had restaurant and she said once he found a big snake dead in one of the big woks that they used to make fries and the head chef suggested that they'll throw away the snake and reuse the huge qty of oil in the pan. Her dad(this happened couple of days after they opened the place) insisted that they should throw away the oil. Eventually they closed down the restaurant business and todate he won't eat anything from any places other than home cooked
