This truck is rather easy to spot from the street, given the perpetual mob of people waiting around for their food. You'll think it's the line when you see it, but they manage to take orders so quick the elation engendered from the short wait in line is steadily eroded by the loooong wait for your number to be called.
I'm always apprehensive about Mexican taco trucks that don't let you put the salsa on the tacos yourself. How do they know what I like? How do they know how much onion I want? Cilantro? I often throw down two kinds of salsas on a single taco, kinda like a little kid who experiments with mixing sodas together thinking they've hit on something incredibly innovative (I can speak from experience and its not that great truth be told, kinda like mixing all the watercolors together and getting brown instead of the magical rainbow you were imagining). So I didn't get to dress my tacos. It turned out ok because not only are they generous and balanced with the toppings, but you are able to request extra sides of salsa.
Which brings me to the subject of asking for more stuff. This truck hooks. it. up. if you know what to ask for. There's some kind of bizarre secret menu of extra sides that they'll just hand you upon request. I only found out because I was lurking by the pickup window impatiently and saw just about every regular take advantage of free stuff. You can get a small bowl of hot grilled onions, sides of their red and green salsa, and a whole grilled jalapeño if you simply ask. It seems like an awful lot of free food, but ya know, ¯\_(ツ)_/¯.
I tried tacos with their carne asada, al pastor, and chorizo. Of the 3 the al pastor was clearly the best, there was a lot of rich flavor. The side of grilled onions and jalapeño were very welcome, especially the jalapeño. Their roasted tomato red salsa is fantastic as well, I wish I had gotten 2 sides of that rather than waste time with their so-so green salsa. But, with a horchata everything did cost a total of $7. Pretty damn good value.
If you're bumming around mid-city, El Chato is worth checking out, but I wouldn't put it on my short list of the best in LA. Just make sure you get the free stuff when you do.
