Basically he is talking about the price of Chicken in Korea is too high.
After He lose weight about 2kg , he became happy and tried to order Chicken, but the price is 20,000 KRW which is expensive price then before.(As far as i remember the price of that chicken is about 16,000 KRW, which I am not sure;) His favorite chicken is Bullroman chicken(I guess its named comes from Korean words, Bull=Fire, roman=only, thus we can guess it taste very spicy and hot) and it turns out its price is different from individual store. [But still too expensive] So he argued that the the government should catch the price of chicken first by comparing it as a real estate.

And from the above you can see he order a chicken and take a picture.
