I've been searching around and really there seems to be absolutely NO Taco Bell restaurants in ALL OF THAILAND???
I read that Yum Yum Corp bought the franchising rights to Taco Bell a long time ago but never opened any. Kinda sad, we've got almost everything for fast food but no damn TB!
I heard there is some place called "Taco Joint" in Onnut, I searched on facebook, couldn't find their profile, but found this screen print from a different site. Any tried it?
