4.75 stars OMG! Hit the jackpot! The foodie jackpot at least. This fairly new restaurant has hit its stride. Great recipes using good quality ingredients? Check. Excellent value for the money? Check. Quick and attentive server? Check. Talented chef? Check. Healthier food choices that are just as yummy as max fat, max carb, max everything dishes? Check, check, and check. Had 3 tacos for lunch today. All yummy. Super messy. Used so many napkins but worth it. The al pastor taco was on a street taco-sized tortilla. No sauce but not dry or greasy. Tender, juicy meat was piled high, giving good value for the money. The veggie taco was on a slightly bigger sized tortilla but it was still chock full of well seasoned, al dente veggies and black beans. The grilled fish taco was on the same sized tortilla. Was especially skeptical about this because the fish portion was tiny. Was fooled because it was hiding under a heap of shredded cabbage. Was so wrong. Portion was just right. Flavor exploded with the combo of eating all components in a single bite. But to earn a perfect 5 stars, Un Taco Mas also has a perfect combo of other factors. The cooks in the kitchen are truly talented. Veggies were crisp tender. Flavorful sauces had some heat but not so much they burn out your tastebuds. Front of the house was just as awesome. The server, Josue, was attentive and friendly but not obsequious. He anticipated every need and checked in multiple times throughout the meal. They're a little shorthanded so he also did triple duty as the cashier and busser. Diana, the owners' daughter, has also served on previous visits. She's very patient and helpful. She's very proud of her mother's recipes. Heartily agree. Food is so yummy. If forced to nitpick, a few minor suggestions. The chips, were fresh, not greasy but a little over salted. Also, the atmosphere, while festive, was a little dark. Change the interior walls from a dark pinkish orange to a lighter sunny orange. And maybe down the road replace the opaque black patio blinds to slightly more sheer blinds. Oh, and bring back the sweet plantains. But these are minor. Tasty food is the driving factor. Am now obsessed. Will definitely return sooner rather than later to check out the rest of the revamped menu. read more

Un Taco Mas is on one end of a large plaza near the freeway, super convenient for a quick meal. I didn't know what to expect from their tacos, but the tortilla was lightly fried! Really liked the crispy crunch with their generous meat portion. I got the carnitas ($4) and just one was pretty filling! Loved the variety of sauces they offered as well. Plenty of parking available, seating options inside and outside, not super crowded. An employee was manning the register alone but was super nice and accommodating. I will be back to try their fish taco! read more

Un Taco Mas - Taco De Carnitas & Taco De Pescado - Mexican Near Me - San Ramon, California

Un Taco Mas is a new place near Starbucks. My hats off to the owner. They were moderately busy Friday at 2PM. This was our first time and also noticed another party that was also new. All of us liked what we had. This is a family run business making it a special place for us. We started with two carnitas tacos and liked the flavors. Their tacos are the smaller street-size and are soft but heated on the grill. Presentation was excellent, sorry no picture today. As noted by another review, the Pescado tostada is ceviche. The server gladly substituted fried fish for the ceviche. The end product, as shown, was excellent. They do a good job purchasing tortillas. They also make their own chips from the tortillas. For a new restaurant, their menu is quite extensive. We recommend giving them a try. read more

Awesome. Highly recommend if you want to eat good Mexican food. We move at far but we continue to go back.

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

The food is fresh . Service is friendly. Location has lots of parking. The place is like your eating at a dinner at home , very tiny but gets the job done. The fact that there is no lunch specials , taco Tuesday I don't think makes ordering a little tricky and confusing . For instance on paper the menu said shrimp tostada. I think though it would be a hot dish but this is basically cold shrimp ceviche. Seafood .Which was the opposite of what I wanted . That is my fault I should have double checked and confirmed with the person working there. On top of that, the my order took forever almost 35 min.4/5 on my first visit. read more

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

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

This place is LEGIT!!! Stopped at the Tesla charger, not expecting much. Got two different shrimp (one regular, one gubernator?) tacos and a fish taco. So much flavor in all of them! Really nice person taking orders as well. Ordered extra orange and verde salsa- didn't even need them on the tacos, but they were excellent flavors as well. Keep these guys going! read more

$$$ 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

Good food, good atmosphere and customer service is wonderful. We got the table guacamole. So huge and entertaining to see it mixed at the table.

Un Taco Mas is such a great New Mexican Restaurant in San Ramon. My husband & I have had lunch there 2 times and the food is excellent.

If you like Mexican food it is excellent!!!! read more

Wow. This is some good Mexican food! The complimentary chips and salsa were fresh and tasty and our tacos were delicious. I really enjoyed my fish taco and shrimp taco which were very fresh and well prepared. The wife had the Birria tacos- fantastic. I'll definitely be back to try some of the great seafood dishes I saw at other tables. read more

I dislike businesses that nickel and dime customers while still providing bad service. We ordered four entrees and were given a small plate of chips. When we asked for more since the food took over 45 minutes to come out, the woman working there said they were extra. We agreed to pay, but then waited another 30 minutes just to receive about eight chips--mind you, there were four adults at our table. The food itself was a disaster: The nachos only had five small pieces of carne asada. The burrito was mostly just beans. The flautas were huge and actually hurt my mom's jaw. To top it all off, our drinks didn't arrive until after our meal, even though we had already been waiting so long. It is definitely not worth the price, and the service is not great. We were sitting near the kitchen where the staff would walk back and forth constantly, yet the actual service was terrible. read more

My Mother let me know when this restaurant first opened and said she wanted to try it out. We were in the neighborhood on July 4th and drove by to see if it was open, it was. We both ended up ordering enchiladas so I can't comment on a variety of items, but we both enjoyed our meal and would be willing to go back. Each plate (entree, rice, beans, w/ chips, salsa) was a little over $20 which might sound expensive but you get a lot of food, and I'm willing to eat leftovers so it was actually three meals and totally worth the cost. read more

Un Taco Mas was a perfect local taco Tuesday casual lunch spot, $20 for 4 tacos, free chips & salsa plus a water. We are trying a new taqueria each Tuesday and this was a nice surpriseThey are counter service but the front of house person also does table service so grab a seat and be served. She was friendly and attentive. Tacos were $4 each we had carnitas, pastor & grilled chicken. My fav was the chicken, hubby always orders carnitas but I didn't try his. The chips tasted homemade and the red salsa was perfect. We will return, it was also nice to read it is family owned business and I was happy to find a local San Ramon spot I'll return too and on a nice day outdoor seating a plus. 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

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

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

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

Excellent quick service Mexican food. Simple but pleasant atmosphere to eat at the restaurant inside or outside and very clean. Staff is friendly and the food is all wonderfully fresh and flavorful. You can really taste that they are using high quality ingredients. Everything feels authentic and home made, our new go to for quick Mexican food. read more

Had a surprisingly good dinner here. My wife had the fish taco plate, I had an asada and pollo taco plate. All were very tasty and fresh. The chips were also good, thick and crunchy, as was the red salsa, which was a little thicker and slightly spicy. Service was friendly and prices were reasonable. 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

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 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
