    Steak fries
    Aldo G.

    Yooo these are hands down some of the best tacos around !!! 10/10 I would recommend to anyone looking for something fresh and savory. The food here is amazing from their tacos to steak fries. Will be coming here often.

    So glad I found this new Gem ! This place has some classics a lot of taco spots don't have like Vampiros! Bomb ass tacos ! And I just can't get enough of there salsa This place definitely hit the spot on some late night munchies ! Meat is so juicy and tender I'll be definitely coming back! Great service as well the Owner and his lady have such good vibes it's overall an amazing spot!

    Cajun Broil

    This spot is great! There is live music or sports playing while the chef makes your food. Definitely enjoyed everything I tried and will continue to explore the menu and tunes. The Cajun broil and the chancla are a must!!!!

Not the absolute best one l've had but still good taquitos were delicious!!! Chicken inside was so tender Guac was yummy! Wish it was a bit chunkier but that's just personal preference. The chips were rly good. Horchata was def my fav drink! Sooo good and I feel like alot of places make it so grainy Service was fantastic and great open space.

    Summary: Flavorful, but HEAVY…read more Details: They just opened up a new branch in SF, but we wanted an excuse to hit up San Mateo, and Latin American is always a good enough excuse. While photos of their SF location suggest some seeing, this OG location is pretty much pickup/delivery only: a fairly literal hole in the wall, located along a random quiet street. Most folks would probably opt to take home or eat at one of the "nearby" parks, but we've gotten in the habit of just eating in the car, which... not so great for something as messy as birria lol. I'll say that for most folks, this would probably easily be more a 4 star spot, while for us, it's more a 2 star since we're unlikely to come back. That's not to say the food was bad: on the contrary, the flavors were quite good, and the consomme was less salty than some of the others we've tried. But their food is HEAVY. Not just the birria itself, but also the burrito we got, and heavier than other places we've been for some reason, with the birria sitting in a pool of oil soon after we picked it up. This probably isn't a deterrent for most people though, so take this as you will. Accessibility: Not too relevant since this is really just a pickup spot, with the pickup window being at the usual height you'd find elsewhere.

When you walk in, you place your order directly with the cashier. If dining in, they will provide you with a basket of chips and you choose from an open table. The booths are a bit cramped with no space at all between yourself and the table but comfortable enough otherwise. There is a self service salsa bar in the corner - we really liked the creamy green salsa. Had just a slight kick but my 3 and 5 year old both loved it. I got a taco salad which is served in a taco bowl with all the ingredients of a super burrito, minus rice and cheese. It was very good, but the bottom of the shell gets really soggy so you can really just eat the top of the shell where it's still crispy. The rest of the family got super burritos and were very happy - the meat was crispy in some parts and moist/soft in other parts and the ratio of the other ingredients were perfect to complement the protein. Everyone left full and happy. Don't forget to get a sweet, cool, refreshing horchata drink to help wash down your meal!

Food- not good they have all the ingredients, but would it kill them to season their food. A little salt maybe while your cook. I had the torta con papas. Carne asada was not seasoned, it was just meat, avocado, tomato and lettuce, once I added salt, jalapeños and a little salsa it actually tasted like something. In all honesty I can't go back nor would I recommend it to my friends and if your Mexican and you like it que vergüenza. One star because they have free refills.
