I've been on a carnitas torta kick, so my friends and I decided to hit our favorite taco truck (Cemitas Poblanas) which is parked on Venice, in front of Smart & Final, in Culver City. When we got there, I remembered that I'd never tried the eponymous cemita, and decided to get that instead of a torta. Sadly, they were out of carnitas (boo!) so I ordered al pastor, which I usually prefer anyway.
The sandwich I received ranks easily among the best I've ever had. Unlike the torta, the cemita comes on a seeded egg roll with avocado, red sauce, and oaxacan string cheese. The roll was a nice contrast to the torta and provided ample structural integrity even as the pork nectar from the al pastor permeated the bread. But the creamy cheese, which comes in little ribbons like cabbage or lettuce, was what really made the sandwich. My main complaint with taco trucks is that the setting usually precludes dairy-based condiments like crema. The cheese provided just the right creamy component that's been missing for me.
We arrived after the lunch crowd and were able to snag the three folding chairs they keep in front of the truck. As we enjoyed our sandwiches in the sun of a perfect LA day, it occurred to me: if there is a sandwich heaven, this must be it.
