Yea it's gotta be McDonald's... Because Nomihoudai( All you can drink) and Tabehoudai (All you can eat) don't exist and aren't popular right? Also Lotteria, Mos burger, KFC, Matsuya and Yoshinoya are healthy and Japanese people only eat miso soup with bits of salad and fish, nothing else. There's no such thing as chicken katsu or okonomiyaki or yakiniku or toriniku. All food in Japan was healthy until McDonalds brought their capitalistic fat American views. YEAH CNN. OKAY.
