Yes this place is a whole in the wall but where else do you get some of the best home cooking food. Stopped here yesterday for lunch after driving in the back country and we were starving. The menu has a good selection and all of it is homemade. I had the #1 (see photo) my parents had the #10 and a ala cart green tamale. The red sauce is the best I have had in a long time. The portion won't let you leave hungry. The price is very reasonable. The service here makes you feel like you are at a friends house, not in a restaurant. Their hours are 6:30 am to 8:30 pm Sunday - Friday and closed on Saturday. Bring cash or check they don't take credit cards ( I can understand with how much they charge per swipe). Good new is the are building a patio this summer for some Arizona dining. read more

Thursday night is ribeye steak night at Casa Rivera. Twice in the past 5 weeks we have gone on a Thursday and they have been out of ribeye steaks before 5:30 pm. So we have decided we will not be going back. read more

Taco Tuesday is the best even my kids have come to memorize the day hoping we order out. Tacos are our fave but everything else is amazing as well. read more

Nice taco shop. Very popular and recommended by locals. Huge carne asada burrito very good.

I didn't even know this place existed until a friend of mine suggested we go here. She is familiar with places in Catalina and Oracle, so we took the drive out. Best salsa in town, hot, and she ordered a milder one for herself. I had a carne asada burrito, and it was the largest burrito I've ever seen. The beef was seasoned to perfection and tender. The plate was adored with cabbage and chopped tomato, my favorite. My friend had a carnitas taco and beans, and hers was very tasty as well. This food is authentic Mexican fare, and I highly suggest you take the drive out to experience this one-of-a-kind restaurant in an old, converted home. No frills, just good food. I want to go back soon. read more

Best breakfast burrito ever! Husband and I stumbled upon this place today while just going for a pleasure drive. Outside a few older locals were on the patio socializing and inside while not fancy, the small cool brick interior was a relief from the summer heat. A comfortable and super casual vibe with friendly service. We were blown away by the quality of the food and vowed to add this to our list of places to return to. I had the breakfast burrito, could only eat half due to generous portion, and I loved it! Husband had chicken breakfast tacos and he was very impressed. We also shared some pancakes and they were divine. Highly recommended! read more

Following a fantastic visit to Biosphere 2, our hungry crew (including two "starving" teens) stumbled across this little gem as we were searching for a different Yelp restaurant. We decided to give it a try and we were pleasantly surprised! Great food including fresh veggies, tasty guacamole, very spicy salsa, tasty chips, and huge portions. Especially popular with our crew were the crispy tacos and combo burrito with carnitas. The waitstaff was friendly and food was delivered quickly. Plenty of locals were enjoying their meals here. One drawback, no margaritas (they don't serve alcohol). Happily tanked up our family of five, including beverages, for $46 and came home with leftovers. It was clean inside and we saw some fun Southwest memorabilia, including old mining equipment outside. They do take credit cards now. Make it part of your Biosphere2 adventure! read more

Have tried a lot of Mexican restaurants in Arizona this one stands out as one of the best ; food is delicious service is fantastic very friendly good prices generous portions read more

Others have commented on the large size of the portions at this little place, but I'd like to focus on the green and red chili burros (yes, burros; they were called that -- and still are-- in small towns like Mammoth, Globe-Miami, Show Low and one place in Tempe, long before the term "burritos" came into play. The first time I saw Casa Rivera burros on the menu at $6 a pop, I almost walked out. Then I saw one. It was like a shoe box wrapped in a flour tortilla. I tried the green; my girlfriend did the red. We both loved them, but had to ask for hefty take-out boxes. One of these things will feed me for at least two, and sometimes three, meals. And you can order them pretty much basic, with just meat (beef or pork) and red or green sauce, or with additives like vegetables, beans and extra cheese. C. Rivera doesn't serve alcohol, but you can bring in your own. All told, I really salute this small family-run endeavor. I lived in Oracle for two years, and during that time there were no Mexican restaurants. Closest was La Casita in Mammoth, and that's great grub in its own right. But Oracle's current little gem is a stand-out in its own unique and flavorful way. read more

I love this place for breakfast. The food is good and hot. Chris, the waiter, is friendly and attentive. Worth the drive to Oracle any day of the week except Saturday when they are closed. Prices just right. They'll invite you back for Father's Day 7-course meal..... a six pack of cerveza and a burrito. My kind of place. read more

I drove by looking for a place to have breakfast and I saw this place that looks rough outside, but what a great surprise. My Huevos Rancheros were delicious. It is a great family restaurant. I was lucky they were open because they are usually closed on Saturday. read more

Casa Rivera's Taco Express - Huevos Rancheros. They were delicious. - Breakfast & Brunch Near Me - Oracle, Arizona

Some of the best hot sauce on the planet. Huge portions, great tasting food but breakfast is to die for. Sausage and eggs and with that hot sauce, I was in heaven. read more

Best food ever!!! There green chili plate is so good! Beans and rice are always perfect! I absolutely love our small town eats.

This is a little dive restaurant in Arizona, not too far from the Biosphere. The food was edible, but there was nothing special about it.

We thought this place would be on our way back to TX from the biosphere 2 so we went to check it out based on the star ratings (we were hungryyy). It was not out of the way, but it was an interesting experience. It's definitely a hole in the wall & looks iffy on the outside, but the food was pretty good. My bf had the green chile beef combo for about $10-11 which was pretty good & I had 3 enchiladas for $8. I'm not a big fan of red enchilada so I was a bit disappointed. It was slightly salty, but pretty good. I wish I'd tried the giant burritos, didn't realize they were huge! Had good service & their salsa was pretty good. read more

Great little joint in the small community of Oracle. Great portions of good Mexican food at a fair value.

The very best crispy chicken tacos in all of Arizona!! Amazing! Every time we go to Oracle for riding we always stop. Tuesday buy 3 get 1 free. read more

Casa Rivera's Taco Express - Huge carne asada burrito! - Breakfast & Brunch Near Me - Oracle, Arizona

Talk about a ton of food for your money. A breakfast burrito will run you $4 & change. It is huge! Most will not be able to finish it. Great daily and weekly specials. Get here before noon on Sundays, it fill up quick with locals. Staff couldn't be more friendly. Family ran business and everyone seems to enjoy being there. For a sit down restaurant, it is ridiculously small. Maybe 10 tables? Not much to it other than it fills your gut for less than $8 no matter what you get. read more

2 important things: 1. Cash only. I can't complain too much. Credit cards take too much money for people who aren't the ones earning it. 2. Not open on Saturday. Really a drawback for people coming in from elsewhere (like me). I had the Carne Asada burro enchilada style and I couldn't finish it. The flavor was good and it was huge. Can't complain. Service is done by family. Well done. The only reason it's not 5 stars is they aren't open on Saturday, but they have a pretty good reason for it (ask them). read more

Awesome place! Will be back, my neighbor was nice enough to take me. Had the ground beef tacos and cheese enchiladas with rice and beans. Will be back to try other items. read more

My husband and I stopped for take-out burritos this morning after hiking at Oracle State Park. I had the vegetarian breakfast burrito and it was not only huge, but also delicious. It was stuffed with eggs, beans, cheese, avocado, and onions. The salsa was also very tasty. My husband had the green chili combination burrito which was also huge and delicious. He asked for jalapeno and loved the spiciness. The person who took our order was extremely friendly and helpful with suggestions. Atmosphere leaves a lot to be desired, but the food is amazing and the prices are fair. We will definitely return. read more

Great spot for New Mexican food! Very cozy little restaurant with amazingly friendly staff. Food is crazy good and abundant! We went for breakfast and our daughter got the half order of the biscuit, egg and gravy special and we took over half home. Can't wait to go back for dinner =) Be aware: they don't serve alcohol (but you can bring your own) and they are not open on Saturdays. read more

Good is delicious! Friendly and fast. Priced reasonably. Had the carnitas combo burrito and it was not dry and so flavorful! He had the carne asada combo burrito and was equally pleased! We will definitely be back! read more

Terrible is being nice! Nacho chips tasted like they were from 7 days ago. Beans were also stale and burritos were Luke warm. I will let you know tomorrow if we get sick! We will not be returning. read more

The service was excellent, I just didn't think there was anything special about the food. I did like the tacos, though. There was something unique about the shell. read more

This is the best Mexican restaurant around. With recent remodel and patio outside. Looks great. Food is amazing. From the breakfast rudy special to the Thursday night dinner ribeye baked potato and Texas toast. I can't seem to get enough of it. The servers and cooks show great hospitality. If your looking for a great place to eat and enjoy a authentic home cooked style Mexican meal Casa Rivera is the place. read more

Casa Rivera's Taco Express - Taco salad was delicious. Will be back forsure! Great service and food. - Breakfast & Brunch Near Me - Oracle, Arizona

We stopped here for a quick bite after the Biosphere 2. It is a small but charming. The service was friendly and prompt. The food was good but nothing amazing. The taco shell was really good. It didn't get soggy after awhile and kept it's crunch. Same goes for the tostada. I loved the salsa!!!! We almost finished off the bottle and there were only 2 of us. It was fresh and had a nice spice to it. I love hot salsas and this one was excellent!!!! read more

Awesome food, large portions, friendly staff. This hidden gem will not disappoint. Best place to eat in Oracle. We will be back for sure!

Located out of city limits don't let the outside fool you. Great authentic Mexican. Homemade shells. Small but friendly. Food was great!

Very good food but the place is a hole in the wall, in the middle of no where but we were hungry and glad they were there only they don't serve beer or wine, which is a major bummer but we were informed we could bring in our own. read more

Definitely worth the trip! Owners are lovely, personable people - you feel like you are eating in their home. Friday night Shrimp Tacos and homemade clam chowder (yes that's right) that would make a seafood restaurant proud. Prices excellent. Important - cash only! read more

Hole in the wall. Drove by it once. Looks like it is closed. Worth the u-turn though. The carne asada is out of this world. Best I have had. Big portions and really good prices. Worth a drive just for the carne asada. read more

The veggie burrito is absolutely amazing. The portions are to die for and and can be split by two people easily.

Excellent restaurant. Nice big plates with lots of food. Food is very tasty and the salsa is hot. You get your monies worth. It's well worth the drive from Oro Valley. read more

Like some folks have commented, bring cash or check - they don't take credit cards. We visited on a Thursday for lunch. Service was over the top - some of the best I have had at any restaurant. The salsas were very good and different, but not so much I would buy some and take it home (BTW, the chips were delicious). I had a Chile Relleno Plate - this is not my favorite style of relleno - too much egg batter - but it was very good. The beans and rice were awesome. I would definitely come back again. read more

Bean burrito with cheese. OK. Not bad. Salsa not that great.

Excellent menudo as well as Mexican potato soup. Beef enchiladas were quite tasty, as were the fall-off-the-bone ribs. Very refreshing home-made horchata. Local crowd and engaging waitress. Reasonably priced, large portions, with a 2nd senior half-priced on Mondays. Home-made chips and salsa adds yet another positive touch to an already great local dining experience. read more

Love this place. Don't let the small hole in the wall atmosphere fool you. Great service, great friendly people and best of all some of the best Mexican food in Tucson. One of our most favorite places. read more

This place is so good after a hard mountain bike ride. Breakfast burrito and 3 chicken tacos hit the spot. To top it all off the best chips and hot sauce. read more
