While we're on the subject of tacos, here's a commercial disaster from 1979 for Jimboy's Tacos in Sacramento, CA. It would be an easy mark to make fun of the dated clothing and cheesy production values, but I won't do that. For their time, these elements probably weren't too far off the mark for local commercials. In fact, they're better than some (most) of the local commercials I grew up watching in the 80's and 90's.
Watch for the camera pan of the menu items near the end of the spot.
Yep, nothing says authentic Mexican food more than hamburgers, french fries, and sub sandwiches!
