I've lived here for 21 years! We fondly refer to it as "taco castle" it has been by far our most favorite place to eat . Was a number one lunch spot for the kids at the high school till mc D came. Local farmers and truckers as well as families etc.! We don't have any bad restaurants in Gustine or Newman well maybe BK but whatever. LOLIf you're driving through stop in you will not be disappointed! read more

The Food is great, service perfect, the place OK... Get the Nachos, are delicious! Our favorite spot every Sunday morning. read more

Great food but I did find a sticker in my burrito once like the kind you see a price on like from a store . I never have any dislikes about this place ever their food is great and the woman who answers the phone is always so polite . I still keep coming back because I understand accidents happen . read more

I love this place. I've been coming here since I was a kid & the food has been continuously amazing.

This place takes ca$h only, is a bit pricey, their food is alright, except for the beans... their refried beans are from the can.

Best Mexican food around! Literally never disappoints. The chicken fajitas are amazing! Chips and salsa are always a must have!

Owner favorite for Mexican food. Great super nachos, tacos, wet burrito with green sauce! Mmmm! Friendly efficient staff too.

Always great food,salsa could be a little hotter,also would be nice if they took atm cards. Service is always great.would be awsome if they had fresh Tortilla chips flour and corn.***** read more

LOVE this place! My daughter is 2 and loves the chips and salsa... tacos al pastor are amazing.. nachos are delicious! Plenty of food.. even a simple bean and cheese burrito is huge.. we love this place.. read more

The food here is fantastic!! If you like Mexican food this is the place to go! My favorites are their carne asada tacos, super burritos and taco salads. Ingredients are fresh and delicious. The inside is a little dated but very clean!! My family is from San Francisco where there is an abundance of Mexican restaurants but they say they can't get Mexican food as good as the food at Taqueria Castillo. I have never had a bad meal from them. read more

It's a gem of authentic Mexican food discovered when I thought of getting off Interstate 5 and avoiding the chain restaurants like Pea Soup Anderson. This is the type of place waiting to be discovered and when it is properly published, will have patrons standing in line for a seat. The food is amongst the best Mexican in California. I'm shocked by the fresh flavors. Better than any $100 a person fancy trendy Mexican restaurant in Los Angeles or San Francisco. Worth the departure off the 5 freeway read more

The service and food are top notch. You really can't beat the prices. Its a hidden gem. The best Mexican food you can find in our area. I love the red sauce on their enchiladas and wet burritos. Great tacos and the best salsa around. The perfect hole in the wall. read more

This is my favorite Mexican place. The tamales and Chile rellenos are amazing. The owners are really friendly and they remember their customers. read more

The food was good (if you don't mind greasy foods that is). The waitress was nice. The chips and salsa was mediocre. The location was um..... (let's just say they can work on the curb appeal a bit more.) read more

Every time I visit Gustine I eat here. Everything on the menu is delicious, the people are amazing and friendly and the food is enough for two meals for me. The carne asada nachos is my favorite.. mmm wish I was there now! PS: If you can.. call ahead and order for pick up because this is a very popular place so it can get busy read more

This is a great place to eat, we were just passing through town & we were hungry. We pulled up Yelp & found this restaurant. The owner was the only one there. He was our host, server &. cook. The chips and salsa was great, my super quesadilla was excellent. My husband had the carne asada dinner. My sister and her husband has the Taco Salad. The food was delicious & the service was spectacular!! It is well worth the time to go there!!! read more

Love, Love, LOVE. This is by far my favorite mexican food place to eat at. Fish tacos are to die for... And the service is great. Dont let the looks of the outside deceive you... You will come back! read more

They used to be amazing!!!!!.......idk what happened. When I was a kid taqueria Castillo had flavor, spice and everything nice in a taqueria. Since.... no. Seems like a band of smelly vegans ran the place down to a unflavorful pit. No spice, no heat. Tacos are hard and the carne seems old. Dry and flavorless. I have since found better tacos at the taco truck in Santa nella rotten Robbins parking lot. read more

I wasn't feeling well and didn't want to cook, so my husband ordered from here. I was skeptical but since I was feeling sick I figured I could skip a meal if it wasn't good. We tried the chicken enchiladas plate, a soft taco plate (tacos are larger) and a few other tacos (chicken, Cavesa, and carnitas). ALL GREAT!!! Carnitas had REALLY good flavor actually every bite of everything was THE BEST! My husband has been here a couple of times prior and he thinks it's under new management or maybe a new cook, because the food was the best he ever had prior. He said it has never tasted THAT good. So if there's been a change it was a good move. Lucky to have a taqueria that tastes like a homemade meal. I'm picky and found nothing wrong with anything we ordered. Now I have a better excuse not to cook! Our new go to! If you want guaranteed good Mexican food stop here. Btw I rarely give five stars read more

Friends ordered take out. Review of food only. (Though I have been inside the restaurant a couple times). Carnitas burrito was huge and packed with flavor. Would have liked some burrito salsa with it, but wasn't included. The carne asada tacos were a hit. The hot cooked chills were tasty. Salsa is great and not too spicy. Fresh chips were the bomb. read more

Wanted real Mexican and the carnitas burrito and quesadilla delivered. So delicious! Muy Bueno!

The last true home cooking anywhere in ca. Everything tastes freshly made. The owner is humble and deserves lot more credit for keeping this place so popular. read more

Awesome tacos, tasty burritos, especially the chicken burrito. Just remember cash only!

Besides finding a bean in my menudo; it was very tasty, nice and hot, perfect amount of tortillas are given, all the right condiments. 32oz cup for $6.95 that's cheap! Only thing is if your order to go they charge you for a plastic bag, which was then put in the tip jar hmmmmm?... Good food tho! read more

Best place around! Super nice owners. Best mexican food. Hasnt changed since I moved here in 1999.

Place of so many high school memories and a fantastic HUGE veggie burrito for cheap. Recommend this to everyone that drives through the area :) read more

Me and My family go here at least twice a month I think it is the best out of Newman and Gustine. The Service is very good just like the food, read more

Every order is better than the last. I can order 10 mins before they close and they happily take my order. I ABSOLUTELY recommend. And trust me I've tried every other place around and been didappointed read more

Amazing good! Clean restaurant! Cheap prices! Can't beat that! The staff is super friendly and they give your food exactly how you asked! Great little spot for gustine .ca lucky to have this place read more

While it's true that I come here mostly because it's near the tracks my train runs on, I can't deny that this joint is easily in my top five favorite taco shops in all of the valley. Can't go wrong with asada tacos, but the quesadillas are great as well. Service is on point and I'm always greeted with a friendly smile. read more

My husband and I used to eat here all the time. I recently stopped going because of their meat. It almost tastes like they cut costs and started using less quality meat. It's a shame, I LOVED their taco salad. read more

Love this place. Great food and great service. Worked nearby for several months and ate here repeatedly- now when I drive through the area I make a special stop just to come here. I especially love the chile relleno. Just make sure to bring cash, cards aren't accepted. read more

I come to this restaurant regularly, and whether we dine in or get take out the server is AMAZING! She always gets the order correct and is incredibly friendly! Very good food at a very reasonable price. read more
