Omanas in Pomona is pretty solid and almost literally a hole in the wall. Cash only, outdoor seating only. Chile colorado is my favorite, get one regular and one as a taco perone, which is any meat in a very good flour tortilla + beans and guac.
1050 W. Holt Ave., Pomona, CA
The El Monte (used to be South El Monte) location of Omana’s was a regular go-to for me. I usually went for the carnitas plate.
