I've been loving the proximity to very good mexican in Santa Ana since moving back. One thing i haven't seemed to find yet, though, is really good tacos al pastor in Santa Ana proper. I've tried a number places, including a few that i would have thought would have good al pastor (I'm looking at you el chilango) but have yet to find good ones. I fact, I don't think I've had any cooked on the trompo here in town. Given the sheer number of taquerias in town, I'm confident there are a number of decent places, I just haven't found them. I've one a lot of searching on these boards too and have found al pastor recs in other nearby cities (farolito jr in Anaheim, etc) but none in Santa Ana.
I seem to remember a few years ago going to taqueria de anda (the one on edinger) and they did al pastor on a trompo... But my memory could be failing me.
