Wendy’s Dave’s Original Double is the best out there in drive through land.
BK Whopper would be the best, but it’s a 1 in 6 shot that you’re going to get a good one.
McDonald’s 1/4 lbers (the only burgers w/ fresh meat) are good if you get a good one as well.
Wendys is my fav
I order them plain or otherwise special and they are often much better being fresh of the grill/cooker.
