La Sierra Taqueria — Restaurant in Antioch

Their service was the worst I've ever had, my order was wrong an I was over charged. I Ordered a simple steak burrito with no dairy and Extra meat that cost me $16. When I recieved my burrito there was cheese in it an it was the size of a taco bell $2 burrito. I only found out about the cheese once I had already taken a bite, but the burrito was oily and flavorless. I do not recommend on waisting your money at this establishment there's a lot of amazing place in the area with high class flavors. I will never visit this place in my life. When the business was in Pittsburg CA, the owner was amazing with the one of the best flavors around, but once they moved to Antioch.

The California Food Administration needs to examine this business to see if it safe for...

This is my favorite taco place in all of east county, only rivaled by the unattractively commercialized La Costa. Their carne asada tacos are so smack, I'm glad I've never been there with my momma, cause I'd probably slap the living pastor out of her. In all seriousness, if you are worried about the neighborhood (murda 9th) then you don't even deserve their authentic south of the border cuisine. East Bay Ridas got your back, and La Sierra got your belly, I've never felt more at home in any other part of old Yoc, and next time I need tires, you can catch me at La Sierra or bonfaire,...

Food is amazing!!! Service is good and prompt. The area is a little sketchy tho, but seeing how delicious the food is, it is worth going there, regardless of the area. Best damn al pastor tacos around. Bar none. The asada quesadilla is also excellent. The Oaxaca cheese and chilli inside the quesadilla really make it pop! The super burritos are really good too. Pretty good size, decent price, and lots of flavor as well. I highly recommend this place. It's definitely my go to local spot for good Mexican...
