What happened to this iconic San Antonio Mexican restaurant on the Riverwalk? It had been 10+ years since I’d eaten here. Used to bring my kids here when they were younger. I’m here on business, so I decided to stop by and have a quick dinner for nostalgia’s sake. Kind of disappointing. To be clear, the service was still very good. Super friendly staff. And the atmosphere and location is good — I mean, it’s on the Riverwalk for heavens sake. But the food was really just average. To be specific:
Chips – 3 out of 5
Queso – 4 out of 5
Pollo Asado w/Poblano Sauce – 2 of 5
Refried beans – 3 of 5
Mexican rice – 3 of 5
Flour tortillas – 4 out of 5 (fresh and hot!)
Seriously, there are so many other Mexican places to choose from, that Casa Rio needs to go back to their roots and figure where they lost their way. Sorry to be so blunt, guys.

We wanted to eat along the Riverwalk. This place looked festive and has a long history so we chose it. I had the regular plate( chili, cheese enchilada, pork tamale, rice & beans and thought it was excellent. My wife had chicken flauta plate and liked it as well.
Service was great and it is a very nice setting along a channel looking down another.

Best restaurant on the river walk, hands down.
The wait was decent on a holiday (~15min). Our server was so kind & prompt – every item came out on a respectable interval, given how busy the restaurant was.
And there was just so much food.
The guac was so fresh. Salsa was so good. Everything was great.
I will definitely come back on my next visit.

Decent Mexican restaurant on the riverwalk. We got the queso and chips and beef tacos with rice and bean side’s. The queso was more like velveeta than traditional queso, it did have a good flavor. The chips were good, light and crispy. The tacos were not that good, the meat was barely seasoned and the taco shells were very thick corn shells which were ok at best. The beans had a good flavor but they were skimpy on the cheese on top. The Spanish rice was very good, light and fluffy. Serivce was good and very attentive. Overall a good place to eat but not if you are wanting unforgettable mouthgasm’s.

It was our first time visiting Casa Rio. We chose to sit outside; the pigeons were readily available to clean up anything that may hit the ground. This didn’t bother us but if you are not a bird person sitting outside won’t be an option for you. Our waitress came to the table with a smile and checked on us throughout the meal. I enjoyed the Chicken Fajita Nachos (minus the beans) and my husband had the Crispy Tacos with beef. The tacos were a more greasy than expected but overall we enjoyed our meal.

We went there for 2 main reasons: vegetarian options and riverfront views and were happy with both.
The server was ok and so was the food – we expected more flavor. The rice was really good. Just FYI, chips and salsa aren’t free but they are very reasonably priced.
We ordered the following:
Salsa – fresh
Queso – good
Guac – ok
Veg fajita – decent
Veg Enchiladas – ok
Vegan chalupa – ok, got tostada
Veg nachos – only bean and cheese, got charged extra for adding jalapenos for flavor

I had an absolutely amazing dinner at Casa Rio! This place deserves more than 5 stars. I ordered the Deluxe Dinner and it was spectacular—everything from the cheese enchilada to the tamale and the chili con carne was incredibly flavorful and authentic.
The Watermelon Agua Fresca was the most refreshing drink I’ve ever had, and finishing the meal with the Sopapillas (hot, fluffy, and sweet with honey) was the perfect ending.
If you are on the River Walk, you MUST eat here. The history of the place makes it even more special!

Apart from being the oldest and the nostalgic view I was not super impressed but Rio. The wait was like 45 mins .. you can get drinks at the bar while you wait. Drinks were mediocre… I have had better back in Georgia 🙂 no free chips you have yo pay! Food was just ok I was not even getting the Mexican flavors. Not Mexican hot salsa nothing. Enchiladas were blah … the only thing cool was the view. I came here thinking of the Mexican experience and was disappointed … I could do a better version myself at home. Oh and the dessert was not that great either

Casa Rio continues to deliver amazing food for decades. It was so amazing. Our server was such a sweet and kind person. The weather was a little chilly so we ate inside. The band would stop by to see if you would like to hear a song. Overall, I highly recommend this location if you are near the river in San Antonio.

Great Mexican restaurant. Prices are very good considering it’s location on the river walk. I had a special called the deluxe plate, it was very good. The chili con carne was a pleasant surprise. Our server Alva provided excellent service. The margaritas are great. The salsa with the chips and salsa is some of the best I have had.
