Hi! I just registered--I registered the second I saw this thread. "OMG, I must register!" I thought.
When I was a kid (in Houston, where I still am), we had a Del Taco down the road a ways. It was one of our favorite fast food stops. I keenly recall the Del Nachos, actually, a good 20 years after the fact.
What I also remember is when the Taco Bell opened up further down that same road. I don't think my parents took me there, but my friend's parents did. I really didn't "get it." The food was so substandard, so not-DT. Yet Taco Bell was packed to the gills. I don't think I understood then that it was all about the almighty dollar. I ate TB's nachos, and they were as nothing compared with DT's. Nothing. It was distressing. Also, that particular TB location had a "backwards" drive-thru--as far as I could tell, the passenger would have to do the transacting at the window.
Anyway, Del Taco was driven out, and I lamented for decades. To this day, I mourn it. I have my favorite Mexican restaurant (non-fast food) about a block away from me, but I wish Del Taco would come back.
I was in San Diego and taking a bus out to La Jolla, and as we drove down some road, we passed--of all things--a Del Taco. But the bus moved on past it, and I just stared out the window in disbelief. I later looked online and found that they still exist--just not here.
