I went to a wendy's in my area recently. They just had a major renovation done. The renovation was fine, but it makes me smile that while Wendy may be the mascot, Dave is still how Wendy's is marketed. There's a photo of him on the wall, and there's a lot of iconography of him around on stuff, with the catchphrase "quality is our recipe"
I remember not too long ago there was a commercial, that i cant seem to find now, that started off replaying an old Dave commercial, before zooming out of the old TV to promote their quality or whatever. it was a nice sort of tribute commercial.
there's even a statue of the guy at their flagship restaurant.
it's nice that Wendy's always sells itself on that sort of "human" element of Dave, the founder.
