Super Junior's Kangin opened up about Siwon's enormous appetite on the October 2nd 'Quiz to Change the World'.

Kangin revealed, "Siwon has an enormous appetite. He's the kind of person to eat a lot. When Siwon exercises, he eats 7 hamburgers at a time. He doesn't eat 1 pizza slice at a time, but 3 at a time."

Ryewook continued, "I also asked for the special Siwon topping, and it was good. The cheese was hot."

Did you know Siwon had such an appetite?
