Ok, since I've finally registered, and not just lurking anymore, I decided I have to tell you guys about the best tacos I've had (I moved down to LA - the westside albeit - a year ago from Oakland, so I've had good tacos). A little place called Chema's Tacos in Whittier on Whittier blvd, just West of Hadley on the North side. (I was inspired by the great Bandini's Taco Quest to do one of my own, and this place is easily better than El Parian)
Get Al Pastor! The Asada is delicious as well.
