If you know, you KNOW! King Taco has been serving up delicious tacos since 1974, and I've been going there for as long as I can remember! The tacos may be mini, but don't let the size fool you--they are PACKED with flavor! The burritos, sopes, and drinks are all too! The place is clean, the food comes out fast, and sometimes there's a line out the door. But hey... when people are willing to wait for tacos, you KNOW they're doing something right! I'm a big fan of the carne asada, but the al pastor? OUTSTANDING! Seriously, I could eat those tacos way too easily. If you've never tried King Taco, what are you waiting for?! Go get yourself some tacos. Just don't blame me when you're back the next day craving more! read more

Many friends have told us about this place as a staple in their area. Came to try it with family and they were good! It was crowded when we arrived, but the line moved fast. It might be a little difficult to hear your order number called if you don't know Spanish. I enjoyed my carne asada quesadilla the most. They filled it with SO much meat, which was appreciated. The carnitas sopes was also very good. Everything tasted like you're eating homecooked meals. The guac it came with wasn't all that spectacular, but it did the job. Overall this place didn't meet the hype I expected BUT I would return based on quality and quantity of food! Service was also great, everyone at the front counter was welcoming. *Pics don't do it justice!! It tastes better than it looks!* read more

Visited 5/20/26 The tacos here are always on point! My favorite place for asada and pastor. The burrito portion size has gotten smaller over the years but the flavor is unparalleled. The green sauce is my go to but if you prefer a kick opt for red. The pineapple juice is a nice add on but you can definitely skip this if you are on a cut. You order at the cash register and then the person preparing your food calls out your number in Spanish. They will ask you what sauce you want there. The vibe is great with music playing from the juke box and families coming in! read more

Don't come here hungry lol cause there is a long wait line to order & a long wait line to receive your food/ order but I think everyone knows that if you've been to a king taco in your life haha The food is good, there are a few things they could fix, the sope taco shells are a bit to hard, so I'm not sure if they are leaving them on the grill to long or not cooking them long enough. They need to be more soft so you can bite through them easily! Also the cashier lady who took our order Sunday was literally half listening, she was looking around like we were placing our order & of course something was wrong when we had already gotten home. Thankfully nothing was missing but my bf ordered an all meat burrito & it was stuffed with rice & beans so he was a little disappointed. Pina agua Fresca is good, I have had better tho! Salsas here are fire! The red is so good & soooo spicy so be careful! The green is delicious & good for everyday, any meal (: Wish the wait times weren't so long, gets a little draining to wait/ stand the whole time. read more

Lack of sufficient employees have customers waiting a ridiculous amount of time to get served. Only one cashier and not enough personnel to complete the orders. It's ridiculous the amount of time you have to wait for your orders. read more

Ordered uber eats, got 2 asada nachos double meat. Ordered cabbage on the side and the pickled jalapeno/carrot/onion/cauliflower on the side. Sooo delicious. 2 sopes asada , the salsa verde was spicier than normal, they didn't forget to push cheese and cabbage on my sopes this time. Horchata and asada quesadilla. Service was quick around 2:30-3:00 pm. read more

Why does it take so long for an order of 1 taco and a side. I orders at 4:56pm and it's now 5:13 and I haven't got my order. What's the hold up. Yes, 1 taco and a side because their tacos are mid, the green and red sauce is why I'm here. They got the best taco sauce in the game, I could eat it with numerous things at home.. it above only reason why I come back here. Service is horrible , customers haggling for sauce with their order is the reason why orders tae so long to come out. 20 min for 1 taco and a 6oz of green sauce to go.. food is alright, sauce is bomb, be prepared to wait . read more

I was impressed with this family-friendly store. I first went here on a recommendation of their tamales and their weekend rotisserie chicken special. The latter was a surprise. The chicken was flavorful and juicy... rivaling Juan Pollo! I thought it was a fluke .. it was not. Going forward, their chicken rotisserie meal will be a staple for our family on weekends. On a Friday at 7 pm, an in-store order took about 20 minutes to complete. Yes, all the tables were taken but there was a seated waiting area for to-go orders that never was crowded. You may have to sit closer to hear your number to be called as their PA system isn't very clear with some employee voices. read more

Gave this place out a try as I am a regular to the Baldwin Park and the El Monte King Taco locations for decades. This place gives a lot of meat for the tacos and the green sauce. Staff clean the restaurant and tables regularly and they have more counters to serve people vs the smaller El Monte locations. My pick is the suadero burritos and soft tacos. And they always give a lot of white onions and cilantros to garnish with them! read more

Went here for late night dinner expecting a fast experience that is in line with other King Tacos that we frequent. However, that was not the case coming in at 10pm on a Wednesday night. There was a line with about 5 parties ahead of ours, but the process to order was extremely slow. Waited in line almost 15 mins just to order. Sat down and thought we'd be called within 10 mins or so, but it was more like 30+ mins, and we could hear all the other people waiting complaining. The table next to ours was waiting and saying, "I just ordered tacos!" They had been waiting 40 mins they said. Not sure if this is how it always is, because we counted 6 people back there cooking, seemed like the normal you'd see cooking at a King Tacos. When they finally called our order, we went up to the counter and our food wasn't even ready yet! They asked what we ordered and started making it! Such a crazy one off experience. So glad we won't ever have to go back to this location. Expected a fast late night dinner and instead ended up spending an hour there before our 1 hour drive home. read more

I had a horrible experience with King Taco through Uber Eats. I ordered two sopes with NO CHEESE, and the receipt clearly states NO CHEESE in all caps, yet they still added cheese anyway. When I called to address the issue, the manager Christina answered and immediately seemed irritated. Instead of taking responsibility, she kept hinting that it was Uber's fault--even though, again, the receipt from their kitchen clearly said no cheese. When I asked what could be done, she said they could remake the order only if I picked it up myself, and offered to throw in nachos for the inconvenience. Literally two seconds later, she took that back, abruptly said "bye," and hung up on me. Mistakes happen, but the lack of accountability, poor attitude, and hanging up on a customer is completely unacceptable. This experience was frustrating and disappointing, and I won't be ordering from this location again. read more

Carne asada is really good I usually get an asada burrito Takes 30 minutes latest 40 minutes waiting in line and waiting for food worth the wait their points system is cool if you come here regularly read more

Had the Asada burrito and it lacked flavor in the rice. The meat made up for it. To be fair, it usually isn't like that, but today it was a little lacking! The spot is spacious and it's busy, but the area has too many sketchy people around. I have no issues with homeless people, but there was a homeless man in line that smelled terrible. Just mentioning it for those who might feel uncomfortable. One thing I'd recommend doing is mixing the red and green salsa. 90% green and 10% red. You'll thank me later! read more

LONGEST WAIT EVER! Even with no line it takes at least 45 minutes to get your food. Ridiculous. Someone needs to check the workers!

I ordered King Taco through Uber Eats and had an awful experience from start to finish. My order was wrong, the food I did get was extremely greasy, and when I called the restaurant to fix the issue, the customer service was unbelievable in the worst way. Instead of offering a refund or any reasonable solution, they told me I had to come in person. I explained that the whole reason I ordered online was because I couldn't go in. I even offered to provide photos of the incorrect, greasy order along with my receipt. But instead of helping, they insisted I bring the food back myself. When I told them the earliest I could get there was Monday (today is Friday), they told me to keep the burrito in the fridge and bring it in on Monday. Seriously? That's their idea of customer service? It was ridiculous, unprofessional, and completely unhelpful. I've never experienced a restaurant refusing to resolve an issue unless a customer physically returns days-old food. I will not be ordering from King Taco again, and I'm definitely warning others about how poorly they handle their mistakes. read more

We waited a full hour for what turned out to be the saddest, most anemic little burrito I've ever seen. This thing was straight-up miniature -- like they accidentally rolled it for a toddler instead of a grown adult. I'm talking bite-sized, half-portion vibes that left my entire family staring at each other like "that's it?" The cooks are clearly on a mission to give us half the food we paid for. Tiny tortilla, skimpy fillings, zero satisfaction. For that price and that wait time, we expected a proper burrito, not this sad little snack that disappeared in four bites. Call it what it is: an anemic burrito. Do better. #AnemicBurrito read more

This is not acceptable!!!! The taco had hair and I see why the place has a low review. This has to be taught throughout the staff that hair needs to be health codes in check. The food has always been a staple for my family and I feel disappointed that this bs happened. The food needs to be looked at before and see all hair is put away in a hairnet. NOT ACCEPTABLE AT ALL!! read more

Every time I come I'm incredibly disappointed about how long it takes to order and how long it takes to get our food. The cashiers move so slow and often there's only one cashier when there is a long line. Then it takes about 25+ minutes to get our food after we order. read more

I've been coming to this location for a few years now. Sometimes it doesn't hit the spot but for the most part it does. I love their carne asada. My go tos are the tacos, burrito, nachos and sopes. Their aguas frescas are delicious but my ultimate favorite is the Piña one. Yes it's always busy. Come with patience or don't come at all. These people complaining about the wait, go to Taco Bell. The cashier and cooks are always friendly. Great ambiance. read more

These guys take forever? I think I stood in line for a half an hour, and then waited another half an hour for the food to be ready. When they brought it out, one of the Sope shell was so hard I almost shattered my teeth. Everybody just wants to have a good experience when they have dinner otherwise dinner kind of gets ruined.... read more

Horrible experience at this location. I've always loved King Taco but this time, was not pleasant at all.. it wasn't busy, they had plenty of workers, ordering was pleasant but then that's where it turned negative. Only 2 people ordered before me, a few people came in after and everyone else got their food first. And what's this process where you order, wait to be called to a window to confirm your order, wait there for the items to be given to the window so they can finish making it. Such a waste of time and process, not efficient at all and they don't even carry simple items like limes or lemons for your tacos. So disappointing read more

I'm only giving a one star review because the cashier lady was nice. The service was terrible!!!! We waited 40 minutes to get our food. They were calling numbers that were way ahead of ours. The place was dirty. My husband had to go ask for our food and that's when we got it. The tortillas for our tacos were dry, the amount of carne asada in the burrito was minimal and it had a lot of rice and beans, the suadero meat was tasteless the horchata was very diluted. MEDIOCRE PLACE!!! NEVER COMING BACK AND DO NOT RECOMMEND IT!! DO NOT WASTE YOUR MONEY THERE!! read more

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. read more

Went to the King Taco in Ontario tonight for the second time, and once again it did not disappoint. The food was really good, flavorful, and tasted just like the King Taco I grew up with. The cashier was friendly, patient, and went over my order thoroughly -- something I really appreciate. A special shout‑out to Hector Lopez, who prepared our food. He was awesome: very friendly, fast, and clearly takes pride in what he does. Our order came out quickly and perfectly. I've been eating King Taco since the original 3rd Street location, back when they were serving tacos and burritos out of the truck on 3rd and Downey Road. I spent many years eating there, and it's great to see that same quality and spirit still alive at this location. Overall, great service, great food, and a nice reminder of the King Taco I grew up with. read more
