Isn't the straight equivalent of Taco Tuesday simply Taco Tuesday?

In the 70s and 80s, there was a donut store in San Francisco called "Donuts and Things." Its logo showed a cartoon donut and hotdog happily holding hands, definitely hetero imagery, and yes, that's what they served. I spent a summer tending the two huge fryers, 8 p.m. to 4 a.m. A hot dog and a donut made a pretty good "lunch", if that's what you call the meal you eat at 1:00 a.m when you're working graveyard.
