Used to love this place. Ever since we moved to Walnut almost 20 years ago, we ate at Osuna's every 2 months or so. The food was consistently good and the service was fine. Recently, the food quality has nosedived. Tonight, we ordered a couple of burritos to go. The amount of meat was small and not all that tasty. They should have described them as rice burritos as that was the main ingredient. Maybe the other items on the menu are still OK. Since the restaurant is very close to our home, we'll give them one more try. However, when we want really good Mexican food, we go to Fonda Don Chon in Covina and have never been disappointed. read more

Took to long to take our order we bounced and hit Taco Nazo down Amar and a hair in my sellsa

It will be worth your while! It seems increasingly difficult to find an authentic Mexican restaurant these day that has great tasting dishes. You can taste quality and flavor in any of the menu items I have tried. The food here surpasses any of the overly salted corporate ran " Mexican Restaurants". I tried the Hollenbeck tonight and thoroughly enjoyed it with the Green Salsa that had a very good flavor without having too much heat from the Chile's. I sure am glad we have this restaurant near home. read more

Your typical family style mex. restaurant. good prices, good selection. I've yet to try something that knocked my socks off, but i do go a few times a year when i feel the urge to get my frijole on read more

I have been going here for years since I grew up right around the corner and still go to school at Cal Poly. The food has always been really good. I really like their enchilada sauce. The service is great. They always remember who my family is and ask about members that are not there at the time, which I appreciate. My only minuscule complaint is the price. But I understand a business needs to do more than break even. Overall, I will always be a fan and I will always come back. read more

I love their buffet: it has a great variety of authentic Mexican dishes and the customer service is great. They make you feel very wanted. Only, bad thing is that they need to get their AC fixed read more

Start w the fresh guacamole it's incredible and the shrimp scampi is awesome. The Sunday brunch is also good and I always get a good table. read more

Love everything about this place. Mexican Beans are the best just like grandma use to make ! Go there every chance I get with family or alone. They are always are so welcoming ! waitress Martha is one of the best and makes a great Margarita! Go and enjoy you won't be disappointed ! read more

Great, delicious, heart warming food. I've been going here for over 10 years! The service is decent and the food is just so good I crave it! I would recommend the soups, burritos (esp hollenbeck), and shredded beef tacos. Soft Tacos + Sopes are not really the specialty so I would recommend going with anything else than what u could get at a regular taco shop. Also highly recommend the weekend buffet! + BEST salsa and chips read more

I came to eat here on Tuesday the 27th around 5 pm. This place is amazing!! The food is really delicious it's actually Real Mexican food! Finally!!!! It taste like my grandmother's cooking! ! The waitress was really nice and attended us really well. read more

My husband and I use to come here all the time when we were dating 13 yrs ago.. food was delish and the service was great. We couldn't get enough of this place. We don't know what happened lately it hasn't been that good. We went today for my birthday and the service was not good, slow with attitudes and the food was okay, nothing special. read more

This is the local "Go to Place" for good Mexican food. We've have had several celebrations there and the staff is more than willing to help set up. The weekday all-you-can eat buffet is tasty. Got my first taste of Potato Tacos. We love their salsa, rice and beans. Great family atmosphere. read more

Honestly..what keeps me going back is the people that work there. The waitress's are super nice and friendly and That's what makes us go back there. The food can be better.... The only problem I have is that I've seen a few times some employees have small accidents and I hope they were OK. And i'm surprised to see the Health Score they received is a "C" ...... I'd like to know why....?? read more

I have been coming to Osuna ever since I was little. Boy is it good. The service has always been excellent. Never once have I gotten bad service here. Atmosphere is very pleasant. Staff is very friendly and always helpful. But the main reason we come here is for the food. The food is and always been really good. I highly recommend going during lunch and getting from the buffet. read more

Disappointed with a Mexican restaurant that doesn't serve fresh guacamole, but will charge you and call it Fresh Guacamole. Went to lunch with my wife for Taco Tuesday $1.50 each, ordered 9 tacos (5 asada, 4 caritas). Ask for side of guacamole, and when we finally received our tacos... all the tacos had green sauce on them. So I ask the waitress for a side of guacamole, and she returned with 2 small sides of green sauce. I told my wife, I guess this is guacamole. Then when I asked for the bill, we were charged $9 for Fresh Guacamole ($1.50 per taco). Yup, not good but wasn't gonna argue about it. Paid it, and yes I did give a tip. I don't see how a Mexican Restaurant cannot have real fresh guacamole? Just terrible! read more

Food is always good. Service this evening was not. We waited long for the orders to be taken, asked repeatedly for salsa, chips, sodas were flat, no extra napkins, never asked if everything was okay. read more

I'm giving the place two stars because of their customer service. I come here sometimes on Sundays with my mom for their breakfast buffet and it's honestly the only good thing about this place probably cause you don't have to deal with the waitresses. Iv come before during the week the 1st time I came I ordered the chicken soup it took almost an hour to get to the table by the time it arrived everyone had finished their food so I took the soup to go and the waitress seemed annoyed that I had asked for a box to take it to go. The last time I was their I ordered the ceviche (I love ceviche its always my go to) iv never tried it here so I thought I'd give it a chance ... big mistake I took one bite and it tasted really salty and not fresh at all when I asked if I can take it back and order something else. I was given a menu and the waitress was really rude about it, said "so are you going to order something else or what" I ordered carnitas taco combination plate. When I got my order it was chicken tacos I decided I'd eat them any way but again it tasted like something they just warmed up in the microwave. The waitress came back and said "we tried the ceviche and it's not salty. So you just didnt like it" she said it as if she was really offended that I had it sent back. unfortunately I won't return. read more

I order a carry out thru the phone the person said it would take from 15 to 20 min I show up at 15 mins I had to wait about 35 min more To bad I paid when I showed up. I dont recommend you going there the wait time its horrible read more

Good food but their service is horrible and the way the expect clients to pay only in cash is horrible bad for business!

Good service. Not crazy about the cheese enchiladas or strawberry margarita. The red sauce was mediocre.

Do not use this place when ordering thru door dash. Not only does door dash charge too much, osunas will rip you off as well. Small portions that they would dare serve in the restaurant. Ex; $8.00 for a 4oz cup of cervice read more

Best Mexican food around town. They have a Great Buffet on the weekends not that expensive all their food is authentic from the chili green chili red chili everything is perfect. read more

I am so impressed by how genuinely good their dishes are; not canned beans nor cheap salsas with greasy meat n cheese like many places are. Generous portions!!!!! I feel like they made it for family. Friendly service, cute decor. I crave to try more of their many other dishes. Their horchata is so goooood!!! read more

Sunday brunch is the best, it's a hit and miss on the selections. I think they try to change it up a bit but I do have my favorites. Ask for the café de oya. The best coffee in the world! read more

Just came here with my husband and almost had a heart attack because I decided to look in yelp while he was washing his hands. I saw that there was a "C" health department score. I, of course, had to check. Is back at an "A". Just wanted to update :) read more

Have been coming to Osuna's for over 20 years now. Lately (within the past year or so) the service is horrible. The food is still good but the service has gone down dramatically. I had stopped coming here for about a year because of this issue and my last visit just confirmed why I stopped coming in the first place. I was sat at a table with no utensils. It took about 10 minutes just to get my drink order. Another 5 minutes to get chips, still no utensils nor my drink. Another 10 minutes to take my order (25 minutes already and my order had not been taken). Finally gave my order, still no utensils and now no more chips. Waited a good 10 more minutes just to get the complimentary soup that comes with your meal. In the mean time the place is being filled with customers and not one person from the staff is acknowledging them. At least 5 bags of to go food have been sitting on the counter since I got there. Finally get my food but still no utensils nor a refill on my drink. The rice and beans are lukewarm at best but still delicious although I've always hated the amount of garlic that they put in their rice. The enchiladas are good but at this point I'm so disappointed with the service that I didn't enjoy them as much. I don't know what it is or why the service has been slacking for so long but it's enough to make me not want to come back and that's a shame. I've started to go to Mayan Tacos and am now going to try Los Amigos (I hear it's delicious). Step up your game Osuna's! read more

I live right up the street from the place. I come here all the time with my dad, its an awesome place to eat with family. There red salsa is the best salsa i've ever had. I come here all the time to pickup salsa for when we have family get togethers read more

I've only been here once. I had a deep fried pork burrito. I don't think it was the best thing on the menu. It was very filling. Because I came there being hungry, I didn't care about how it tasted until I was starting to get full. Just like what I said I've only been here once, so I can't tell whether the food was gross or it was only what I had. read more

I love the food here. Places don't have chili rellenos. They have it here and it is so good. The portions are very generous. Hollenbeck burrito covered the whole plate. I had 2 item combo, chili rellenos and 2 taqueria. Couldn't finish it. Had to take it home read more

Everything we ordered was absolutely delicious! We are going to use them next week to cater approx 60 people for our fundraising event. :-)

This little gold mine is awesome, good food, good service, margaritas grow on you, haven't had a bad experience yet, went to taco Tuesday's, fish tacos are super delicious, can't post nothing negative, everything is very good! read more

I usually come here for just one thing. Lobster burritos, homie!!! It's pricey though ($13+) but they hook it up with the little lobster tails. Trust. Everybody else that reviewed it likes the place. Friendly service too. read more

I've been coming here for years and they never disappoint! Food is the best I've had anywhere and the service is exceptional. I think they know me by now because I come so much, or if they don't, they make me FEEL like they know me! Definitely definitely DEFINITELY do their lunch buffet!!! It's SO good, with a great variety, AND they change it up everyday practically. Plus, it's a buffet! Who doesn't like buffets?? Thanks Osuna's for always feeding me!!! read more

This place. Their lunch buffet was not good. It lacked favor and it just tasted inauthentic

My man loves this place. He loves to get the carnitas pack, you get a lot of carnitas, rice, beans and picante sauce. My favorite are the chicken taquitos with guacamole. We usually order to go and eat it at home. It is nice there also but since we live nearby, we prefer to eat at home. read more

It had been about 10 years since I had come to this restaurant. My friend and I went there last night for dinner, and all of sudden I remember why I stop coming.... The food simply isn't good!!! I order a carne asada taco that came with beans and rice. The taco was awful! They wet the tortilla with oil it seems like. When I tried picking up the taco it fell apart! It was a soggy taco!!! The taste of the meat was bland and super greasy!!! Rice had a weird unpleasant taste, beans were ok. Food was a Luke warm temperature. Now please pay ATTENTION to this: while we were paying I notice one of the cooks pouring a green salsa into a different container. To assure he pour everything out of it he used his two fingers and scoop the remaining salsa into the container!!! I was so gross out!!! Where is the sanitation and cleanliness!!! Osunas have you heard of cross contamination, food poisoning!!! I really feel that the owner of this restaurant needs to give training to his staff regarding food prep,sanitation,and cleanliness. While he/she is at it give them training on how to prepare food that actually taste good!!! Needless to say I won't be returning!!! read more

Been coming here for years. I live right around the corner. Usually get the burrito ranchero when I do a carry out. I ordered the chicken enchiladas and they were really good. The chips, salsa, and guacamole were really good. Service was good, can't complain one bit. I'm only given it 3 stars because it was pretty warm inside. Maybe cause the kitchen was right there where we were sitting? But with it being over a 100 degrees outside and it being warm inside made eating inside unenjoyable. read more
