In n Out Burger.
And I second Taco Bell, but maybe that’s just because I crave Mexican food so much in Taiwan.
Taco Bell is the BOMB yo. 
In Taiwan? 五花馬 (“Five Flower Horse”). Their Cantonese fried rice and their beef rolls are great.
Seems popular and growing chain after what seems like a dying company, The parent company, Tim Horton’s now needs a fix in the States (still the national icon though in thier home)

I’ll be back in California next week and I’m going to make a valiant effort to hit up all of these 
Lots of folks on here like Taco Bell. But y’all know that they don’t use real beef, right?
Checkers.
That was a rumor and I think they sued people making that claim. It is beef.
Arby’s, I read on this forum that it used to exist in Taiwan
Taco Bell, jealous that Korea gets to enjoy it’s goodness and hope one day it will come to Taiwan
I should have said not 100%. Part of it is TPV.
