I want to recommend you what I think are the best Baja Style Tacos in Los Angeles.
After trying many, many recommendations, I finally found what I see as the real thing, these are not a "Los Angeles Style Baja Tacos'" ~ these are truly authentic Northern Mexico / Baja Style Tacos! That's Mexicali leaning towards Sonora.
You might want to read more about them in Yelp, also a few online local blogger reviews had come out in the last few days.
For now they are located at the corner of 1st and Beaudry in Downtown Los Angeles, but they might be moving locations soon. The best is to check their Twitter feed for actual time and location.

For now I know they are at 1st and Beaudry, Wed-Thu: 8 pm - 12 am and Fri-Sat: 8 pm - 2am.
