No, it's not what you think.
When we were in Scottsdale we passed by a restaurant being built called Pink Taco. Mark and I both commented on the name, finding it out of place for the chic suburbs. I promptly forgot about it.
While watching Saturday Night Live they made mention of the Pink Taco and the problems they are having with the local community in Scottsdale. Of course this reminded me about the restaurant and prompted me to post.
Do I have anything to add to this? No. I just think its a pretty damn funny name for a restaurant. Or a strip club with a Mexican theme.
