La Fiesta Mexican Grill at 22441 Antonio Pkwy in Rancho Santa Margarita serves up straightforward, approachable Mexican food with a fast-casual vibe that fits neatly into the everyday routines of locals craving a quick but satisfying meal. This spot, blending Mexican and fast food styles, makes a particularly strong showing on busy nights like Taco Tuesday, when the lines stretch out the door and the kitchen churns through popular items like crispy chicken and battered fish tacos.

The atmosphere is lively and functional rather than formal—think bright lighting and a steady flow of customers grabbing carryout or settling in for a casual bite. The pace is brisk, yet the staff take care to accommodate specific requests, such as dietary adjustments, without fuss, which tracks well with the friendly service often mentioned by regulars.

Menu highlights are clear crowd-pleasers: nachos, tortilla soup, and hearty burritos loaded with carne asada, chile verde pork, or chicken mole. The shrimp quesadilla and fish taco are popular picks for those who want a fresh take on coastal flavors without slowing down. For something sweet, fried ice cream offers a familiar but satisfying finish. The accompanying chips and salsa have a fresh, homemade taste, reinforcing the casual but quality-first approach to ingredients.

La Fiesta suits busy locals looking for a dependable, flavorful meal after work or on weekends, especially during special deals like Taco Tuesday. The presence of aguas frescas and margaritas means it can also serve as a casual spot for a relaxed drink with friends, though it’s primarily focused on food. Bring an appetite, especially if you’re eyeing the carne asada egg torta or the generously stuffed burrito plates — portions lean toward hearty rather than light.

Overall, if you want freshly made Mexican comfort food without the wait or formality of a full-service restaurant, La Fiesta is a solid go-to. It captures the no-nonsense spirit of Rancho Santa Margarita’s neighborhood dining scene, ideal for quick stops, takeout, or casual gatherings where flavor and convenience come first.

Always a great experience with great food! I usually get the shrimp tacos but I’m on a special diet and just needed 2 chicken breasts for the day and they accommodated my request with no issues. Tasty!

What a treat! Was back in town for family and realized I could get dinner here - yea! It’s been so many years… will it still be great?? YES! A Thursday evening and, happily per usual, the line to order was out the door. The food is that great! Really. I usually choose takeout and considering the fast pace and large volume of customers it’s incredible I have never had one single mistake made in over a decade. This is the only restaurant I can say that about. Their quality control is amazing. They have dine-in, lovely outside patio tables scattered around a beautiful courtyard and a gorgeous, lit fountain. Great casual ambiance. Plenty of free parking in this shopping center. You will order at counter; thereafter a sweet lady (who’s been there as long as I’ve known about this place) will bring your orders, and also check on you if outside. It just all works wonderfully and then you get to eat! ¡Visita pronto y disfruta!

Excellent tacos for taco Tuesday! My absolute favorite is the chili Verde wet burrito. Absolutely insane flavor. Make sure you're hungry as this burrito is a MONSTER! The picture was a previous take out

La Fiesta is the best Mexican food west of the Rio Grande! The freshest Ingredients, fresh roasted salsa made daily. By far the best I have had since living in Texas. You have to try it!!!

Found this nice family owned shop while visiting family in Rancho Santa margherita. The friendly welcoming staff greeted us and took our order right away. It wasn't too crowded so we sat and waited for our food to come over. The food took no time at all and was very tasty. Tacos and nachos were good and flavorful. The salsa was fresh and hot. Overall a nice spot with good food and definitely reasonable prices. Give them a try

Still, one of the best Mexican restaurants in Rancho. Even though I don’t live around the area anymore, I still come up here for the delicious food. My wife and I love it. The food is always fresh, tasty, full of flavor, amazing! They also offer a few different brands of beer and two choices of agua frescas. Horchata, Jamaica, and/or Tamarindo. All very good choices. Love that they still offer outside seating as well as inside. The cashier and all the inside personnel are very welcoming, friendly, helpful, and quick. Still a highly recommended Mexican restaurant!! ——————- Still one of my favorite Mexican restaurants here in Rancho Santa Margarita, Ca. They know us here already, lol, we are regulars here! Their salsa is really good. We usually buy the salsa every time we go to any of our friend's house to eat. They all love it too. The food is delicious and fresh as usual. You can seat inside or outside. Parking can get busy depending on when you show up.
