Chi Chi's
It wasn't downtown but I miss Señor Pablo's.
I think Merci Sueppel was involved in both of those restaurants and they were two of my favorites. I also remember the suit of armor when you walked into Señor Pablo's.That and LaCasa. I was a little kid, but, I seem to recall a suit of armor just inside the door at Senor Pablo's? It really classed up the #5 special I ordered.
