I’m not sure what Wendy’s appeal is outside the US.
In the US, I used to eat there once a week, when they had a location near my house. They closed that one, and now it’s about 2.5 miles to the nearest one. Unfortunately, there is a Chick-fil-a, Whataburger, and In-n-Out burger nearby, so they get no business from me, lately.
I’ve eaten at Wendy’s outside the US, in Central America and Asia, and they were even less appealing there.
