I love the food. I always come early but today I came like around 11 at night and let me tell you the long lines and people were just cutting in line because they placed their orders through Phone. They should have a separate line for them not just cutting in front of us that we’ve been waiting for 40 minutes. But I love the food love the atmosphere. Customer service was OK.

King Taco never disappoints when it comes to flavor. The al pastor tacos are juicy, well seasoned, and incredibly satisfying. The red salsa is on another level, bold, fiery, and addictive. It brings serious heat that lingers long after the meal, but that is part of what makes it so good. I honestly wish I could take a large container of that sauce home because it makes everything taste better. Always a memorable and delicious experience.

I had the worst experience last night with a certain worker. I did not catch her name but she was short, darker skin tone, glasses, and wears a bun. It is not my first time though with her !! 2-3 weeks ago I came and had an order. I was waiting in the seats the whole time. Keep in mind it was only carne asada nachos so it’s something simple. I wait for more than 30 minutes and realized other numbers after me kept getting called. I went to go tell her and she claims I did not hear and put my order aside when she never even called it! She was telling her coworker about me claiming how I apparently left and was how I was barely getting my order with the nastiest attitude. She just tried to keep fighting it with me. She was trying to make me look stupid when I was sitting down the whole time and never called out my number.I did not appreciate that. Now I come in last night, once again ordered carne asada nachos and encountered that same worker. I left the building confidently and when I got home I opened my box and it was just pure cheese when I had ordered CARNE ASADA nachos, I wish I snapped a picture of that. I go back to her since she messed up my order and told her about it. She then wants to use the same box when it was already a good 30 minutes that passed. Why would you use the same box if the cheese is already cold? Makes no sense. I asked her can you redo them again and once again she tried fighting it with me. I opened the box back home it was barely packed with cheese and really little meat just in the center of the box. Once again I should’ve snapped a picture but I did snap a picture of how it looked like after a few bites. No meat and no cheese!! She barely put anything after I asked her to remake it as the other nachos were cold. I wanted to so bad go back again but it was just too much already. I would’ve asked for a refund and spoke to her manager because this customer service is honestly the worst I have ever experienced. She has not done me bad just once but twice. I will never be going back to this location again. The most rude worker I have encountered.

First off I will start by saying this isn’t my favorite location. cuz some, NOT ALL señoras aren’t so nice, so I come out of convenience. Last couple times i went to this location I seen a couple new faces, one person (Fernando) in particular went above and beyond to ensure I had the best experience. His customer service was very impressive. He served me the best tacos !! After having his immaculate service for the second time I’m more eager to travel to this location. Thank you Fernando and king taco for hiring him!

The moment I got off the plane from Oakland, this was the first place I had to go. This place is awesome, guilty pleasure and long standing tradition in LA. If I have the time, I always come here for al pastor tacos, some language and some cabeza. It is so good. Sauce on the side is a must.

King Taco is consistently a fantastic place to grab a meal. Each location delivers flavorful tacos, burritos, sopes, and a variety of other dishes that never disappoint. Every visit is satisfying and leaves you looking forward to the next one.

Ordered ahead yet, they still make it 20 minutes late, cheese machines were empty on both sides, they had to reset the machines. Everyone in line was waiting, while no body was tending the front, yet staff was filling orders without ck’ing on how long the line were increasing. Lines are for online customers, door dash, Uber eats & other’s. (Slow response from staff) Mostly food is premade, just need to fill orders. Maybe take a page from In-N- Out everyone has a particular task!! Just my opinion

King Taco is my go to spot for Carne Asada nachos. The flavors are incredible and the red salsa adds the perfect kick. It’s spicy enough to make your eyes water and lips tingle, yet every bite is totally worth it. I always leave craving more.

I had the worst experience at this location. The wait time was extremely long — after placing my order, it took over 40 minutes to receive my food. That alone was frustrating, but it got worse.
When I finally got home and tried to eat it, the food tasted really bad. The flavor was off, and it did not taste fresh at all. I ended up throwing the entire meal away because it was not enjoyable.
I usually go to the Baldwin Park location and rarely have issues there, so this experience was very disappointing. I definitely will not be returning to this location anytime soon.

I’ve been to this King Taco location several times and its always a good food experience. Afternoons and late night, their service is fast even when the line is long. Tables and floors are clean and they have a jukebox for entertainment. I’ve had the chicken, carne asada, al pastor, suadero, and carnitas. The meat isn’t overly seasoned so it allows the natural flavors of the different meats to come through. The carnitas can sometimes be a little dry and the suadero doesnt always have those crispy edges, but they are still yummy. With a variety of menu options (tacos, quesadillas, burritos, sopes, nachos, tamales, rotisserie chicken, rice and beans) you’ll definitely find something to satisfy a party of 1 or 100. I prefer this location over some of the others because the food preparation and flavor is consistent. Definitely worth a try!
