Korean Fried Chicken Nutrition

I would wager not many. I don't personally know of any big chain Korean restaurants. The FDA only requires restaurants with 20 or more locations to provide nutritional information. Meeting the FDA guidelines is expensive as it has to be done by a lab and would be a financial burden on small mom and pop, local restaurants.

It wouldn't be significanlty different from KFC in terms of energy or nutritional value. You're mainly dealing with chicken that's dredged in some sort of flour, packed with sodium and then deep fried. You could argue it is better quality than KFC but nutritionally the differences wouldn't be much.
