Excellent food and great service in this family-owned gem. Went there for the first time this past week for dinner, and thoroughly enjoyed the taco salad with carnitas, as well as the yummy flan with a chocolate sauce drizzle. I will be back! read more

The food and service was excellent. I will be telling friends and family about this place.

Had lunch here. Tacos were great, service was excellent, food came out fast, they did provide free water and chips/with a red and green salsa. Will definitely return. read more

My husband and I had a great lunch at Un Taco Mas today. I ordered the plate with two tacos and rice and beans. The rice and beans were some of the best I have ever had. My tacos were excellent. They were moist and piping hot when they were delivered to my table. When we walked in the owner was very friendly and made us feel very welcome. I thought the prices were very fair. We ate inside for this visit. However, I did see a very large outdoor eating patio. When I come back, I will definitely try the outdoor patio. If you are looking for a new casual Mexican restaurant with authentic Mexican food and a great vibe. I highly recommend Un Taco Mas. It is right on the corner when you pull into the shopping center. Off of Al Costa and San Ramon Valle Boulevard. If you drive towards the middle of the shopping center. There is lots of good parking. read more

Un Taco Mas - Two taco combo plate with rice and beans. Muy Bien. - Mexican Near Me - San Ramon, California

$$$ Surprisingly more expensive than I expected. Lunch for a family of five came to about $150. Service was stellar. One gal was running the entire front of the house, and she was very nice. Kids meal of fish n chips was not worth the money. read more

This place earns a strong 4.5 stars from me. Right away, the green salsa with the chips tells you everything you need to know. Fresh cilantro floating through it, bright flavor, and then that hidden surprise -- little pieces of avocado mixed in. Absolutely addictive. One of those salsas where you keep saying "just one more chip" and suddenly the basket is gone. The michelada? Bravo. Frosted cold glass, fresh shrimp still steaming when it hits the table, clean presentation, balanced flavor, and made with actual care instead of just dumping ingredients together. Easily one of the best micheladas I've had in a long time. Simple, fresh, and executed the right way. Now the tacos. First off: the freshness of the meat stands out immediately. Honestly some of the freshest I've had recently -- and I grew up eating at Los Pericos since I was a kid after haircuts next door with Randy and Chief. Lately though, Los Pericos has slipped a bit on consistency and quality, and this spot reminded me what fresh really tastes like again. A couple honest notes because I actually want this place to win: * The carnitas were slightly dry. * The carne asada needs a little more seasoning and marinade depth. Right now it tastes like fresh meat in a tortilla instead of that classic Mexican asada flavor profile. The salsa ends up carrying the taco instead of complementing it. But even with that, the foundation here is strong. You can feel the effort. The ingredients are fresh, the plating is thoughtful, and the food feels cared for. I genuinely hope they stay in town because the restaurant business is brutal -- and trust me, I know how hard this industry is. My biggest hope is that once the lunch rushes start getting crazy, they don't cut corners or lose the quality that makes this place special right now. read more

Un Taco Mas - Quesabirria with dipping gravy - Mexican Near Me - San Ramon, California

Dianne is so nice and gave the best customer service! Enchiladas Rojas had a delicious red sauce. I ordered Al Pastor, Carnitas and shredded chicken. Al Pastor was soft and tender and had great flavor. Carnitas were cooked to death so couldn't chew that. Shredded chicken was moist and a great choice. The plates or platillos come with rice and beans and no complaints with the refried beans. Really good size plate especially for one person. Small tables inside but a great patio to sit outside. I'm excited to go back and try more of what they offer. The only downside were the carnitas meat and the prices are pretty high for a family outing. Flan was a good dessert although didn't need the cheap chocolate sauce on top. I'd take it plain with that whipped cream. Kids had the super quesadilla and they loved it. read more

Un Taco Mas opened up recently in San Ramon's Gateway Center off Alcosta. For a relatively small restaurant, they have a sizable menu of Mexican cuisine, including birria, seafood-centric rice and bean plates, and like a half dozen varieties of soups, ranging from classic pozole to a seven-seafood soup. This place has potential, but during our lunch it felt like a soft opening: 1. None of the soups were available. Yikes, the wife really wanted to try the 7 Seafood soup. 2. The menu above the order counter was all on Spanish with no pictures. They do have a nice menu book in English with lots of pictures and detailed descriptions. 3. The kitchen seemed overwhelmed with Doordash orders and food came out slowly for the handful of dine-in customers. 4. I thought I ordered grilled fish la plancha but we got a grilled shrimp over onions. The wife was hungry and decided to eat it. Shrimp were overcooked, rubbery, and under-seasoned. All the wonderful flavors went to the onions (2 stars) 5. My Chicken Mole was a bit better - two large boneless chicken breasts that were on the dry side. However their mole was excellent with sweet, sacory, and mildly spicy overtones. (3.5 - 4 stars). Willing to come back in the future when the full menu is available and the kitchen is able to keep up with orders. Fish and octopus feature heavily in many dishes so we'd probably try those next. For now, 3 stars. read more

Well we seen the sign on the corner, and we are always looking for new Mexican food near us! So we decided to give them a try tonight. Glad we did! My wife got the nachos with grilled chicken, she liked it and could not finish them. I am a mole' snob, and this was pretty good! Had a slight spice to it . Chicken inside was plenty. We will be back! read more

Been looking for a local restaurant with good chicken mole. Think I've found it. Still not as good as one I've had in San Francisco but really good for the Tri-Valley. Un Taco Mas just opened up in the same strip mall as Luckys and McDonald's, on the corner of Alcosta and San Ramon Valley Boulevards. Located in the storefront that used to house a chocolate store and more recently an Indian restaurant. Hidden by waist high hedges is a small dining room with a nice and secluded outdoor seating area. Order at the cash register and they bring your food to the table. So imo, what makes this good mole? Rich and complex sauce that's very well seasoned. Savory, a little sweet from the chocolate, mildly spicy from the chilies and nutty from the seeds and nuts. Used to frequent a restaurant in the area that made good mole but during COVID lockdown, they changed their recipe. While it still looked like mole, they had diluted the sauce with chicken stock. No mole taste left at all. Have been searching for a replacement ever since. Another big plus, think the tortillas were made fresh in-house. Can't wait to try them in other dishes. Another bonus, Un Taco Mas has fried sweet plantains! Loved that these were fried naked, without batter. Lucked out since they claimed they really didn't have enough for 1 order. They sold it to me anyway. Yes, could have done with a couple of more pieces but with 8 thin slices, it was enough to share a taste with my sister. So yummy and sweet enough that the jam garnish was superfluous. So why only 4 stars? They had a huge menu but some puzzling absences. First no agua frescas. They only sold bottled drinks. Would love watermelon, horchata and cantaloupe agua frescas. Next, the mole sauce was great but the chicken was a little dry. The sauce helped alleviate this but still. Maybe offer choice of (lean but drier) chicken breast or (fatty but juicier) leg quarter. Then, while I actually liked the chunky refried beans, they were luke warm at best. Another con, no chips and salsa bar. Lastly, been back a couple of times since and they've been out of the fried sweet plantains. The nice surprise was the leftovers. Loved the large portion. Only ate 2 of the 3 chicken enchiladas. Took the 3rd home and ate it for dinner. Reheated, the mole actually tasted better, spicier. Yummy before but was elevated to another level when the chilies were activated. Great potential. It is only their soft opening, not a grand opening. They're still nailing down the menu so not everything is available. I'll revisit after they've worked out the kinks. Please just don't mess with the mole sauce. read more

After a disappointing first experience we tried again and were pleasantly surprised! If you've read my previous reviews on Mexican restaurants you will know I'm super picky. I prefer So-Cal taquerias and Un Taco Mas delivered. I had a carne asada taco and tostada de camaron. The carne asada was perfectly seasoned and not hella greasy. My taco never got soggy which is appreciated. The ceviche was super fresh, generous portion and well balanced. Nothing was overly salty like most places nearby. My husband got the red enchiladas and they were delicious, the sauce was just spicy enough and rice is often overlooked, the grains were nice, fluffy and separated. You can tell the family takes pride in their food and we felt like we sitting in our Tia's kitchen having a meal. read more

Bad service once they had a good grand opening it became one of those places that I mention before I guess you gotta look a certain way to get good service don't know why certain restaurants do this I mean we pay the same way and we pay to get our order right no more money for people that own businesses and don't know how to treat there customers read more

I always get their quesadillas which are really good, I really enjoy them but the only issue is have is that there is never enough sour cream or guacamole, they put enough for about 2 bites and that's it! I understand avocado is expensive, I work in food myself, but it would be nice to get a little more to go with the 3 quesadillas that I get. read more

Tried this place for the first time, and won't be back. Overall the food was bland and lacking flavor. The prices are high as well, which would be ok if the taste was better. Super burrito with carne asada might as well have been a bean and rice burrito. Sadly, the chips we ordered with the $9 chips and guac were completely stale. Salsa guac was good but biting into soft chips was dissapointing! Maybe some of their shrimp or mole options would be better, but if you can't nail the basics.... read more

If you love waiting for your food, this is the place for you. Came here to try this new place out, a little early before the dinner rush. 25 minute wait for the tacos to get to the table. And only a few people got their food. 37 minute wait for the burrito to be served, and everyone else at the table had just about finished their meal already. Quality of food is meaningless after waiting that long. In a nutshell anyway: meh. Nice and friendly staff, although you need to ask for most things (water, the drinks we ordered, more chips) and then they were responsive. Sad to say, won't be back. read more

Do not order online from this restaurant. I scheduled a pickup order for the exact time I'd arrive after work, but when I got there, they told me my food had been sitting out for an HOUR. Apparently, their system doesn't account for scheduled pickup times, so they make the food right away. This was especially disappointing since I ordered fish tacos, which clearly don't hold well that long. Even worse, they didn't offer to remake it--just to microwave it. Really disappointing experience, especially considering the great reviews on the food. I expected much better. read more

Super excited for this new taqueria!! I came on Tuesday . Got a birria taco and a pescado(fish taco) both were EXCELLENT! Flavors on point!! I loved them so much went bk on Wednesday!!

I had tried this place earlier but never got the chance to review it since it wasn't on yelp yet! The first time I got the quesabirrias and it was phenomenal. I didn't eat it there but the whole car ride home it was still so fresh! I was very impressed by this. The second time I went I got the regular burrito but with the option of birria as my meat. Next time I will have to ask for consomé to dip my burrito in! The cashier/waiter was also very nice! They had cool piercings that I've never seen before. They were also playing the best Hispanic music to wrap the vibes up as a 10/10! read more

So as we were at Starbucks today I looked over and saw that the crappy pizza place is now a Mexican place. Ummmm coool! Walked over to check the menu, saw the prices were really good and decided to order some food. Chicken nuggets?! Hell yeah. My kid only eats chicken nuggets. Ordered some tacos, nuggets, guac, and a quesadilla. All solid. Best part? $36 for four of us. Coming back like 3 times a week now. Tacos are amazing. read more

Went here for the first time and we were pleasantly surprised. I could not tell you the last time I left a restaurant with dinner for two and 2 beers for under $40!

Still need to try some go to items like the chile relleno but looking forward to the next visit! read more

Both had fish tacos and they were delicious and large. Rice and bean great too. Glad to find a place so close to home.

Tried Un Taco Mas for dinner and ordered the carne burrito. It wasn't very authentic, and surprisingly didn't come with any fresh salsa--just bottled green and red sauces on the side. They also don't offer water, so you have to purchase a drink. Overall, a bit disappointing for the price and experience read more

This place is very underrated. The food is pretty good for being around here. It's better than Casa Orozco. Which is pretty low as it is and better than tacos azteca which is pretty nasty to me. I have already returned twice and had different items and for me. They were very good and very well. Made. The only fallback is I don't have a bar. read more
