General Info
Over the centuries, all who found their way to this area have been blessed by the river and the abundance of life that its water has provided. For the native American hunters and gatherers, the numerous deer, bear, mountain lions, alligators, raccoons, squirrels, cats, coyote and javelinas provided ample meat along with fish and water fowl. The Spaniards, exploring their way north out of Mexico through deserts and semi-arid South Texas, found the timber, fertile soil, and clear water well suited for their purposes of settlement and colonization. The river, first named St. Anthony de Padua, was soon diverted into channels and acequias for irrigation of fields and household use. The first bridge built to span the river was here at Commerce Street. The priests at the Alamo were afraid the easy access by the soldiers from the garrison would endanger the women of the mission. The bugle call of "El Deguello", from Santa Anna's army came from these banks. It signaled, no quarters, utter destruction, and no mercy for the defenders of the Alamo. As the mission period gave way to a more established society, the river was used for numerous bath houses natatoriums, breweries, and mills. San Antonio began a romance with the river with festivals, fairs, parties and picnics on the banks. The restaurant founded in 1946 by Alfred F. Beyer, sits on land first granted title in 1777 by the King of Spain. The Spanish Colonial period hacienda became the core of the new business. The cedar door and window lintels, the fireplace, and thick rock walls, are still evident inside the building. Casa Rio was the first San Antonio business to open its doors to the River and take advantage of the River's setting. Canoes, gondolas, and paddle boats, evolving into tour and dinner boats, began here and helped create the Riverwalk of today.

After looking for authentic Mexican food we landed here and was welcomed by the best waiter Zappo...he was very knowledgeable and very polite with our food request and even talked us into some favorite drinks from the local area. My girlfriend and I rate this place a 5 stars for great food and awesome wait staff...great location on the river walk also. Thanks Zappo!

Hair in 2 out of 4 plates

Took out of town guest to lunch today and food was taste less and then my grand daughter found hair in her beef enchiladas. Then I looked at my food she and I both ordered the same plate and guess what there was more hair in my plate then in her's the waiter offered to bring her another plate 25 minutes later so by the time her plate got there she had already lost her appetite and so had I. Even though they removed her plate and half off of mine the bill but for two other plates and 1coke 2 teas still came out to $29.00 not including the tip. It was really bad service and bad food. The manager was very pleasant i said the waiter Sapo I'm sure could have brought out our plates to our table sooner, cause by the time they got to us the food was semi warm not hot

Crappy Service!

Went to Casa Rio tonight for dinner... it looked nice, too bad it did not end up nice!

Still fuming... asked my waiter where the bathroom was, gone less than 5 minutes! The busboy cleared my table of my dinner (only 1/2 eaten) and a full platinum margarita, and was seating someone else at my table when I got back!

Waiter was mortified, tried to get me a new table and drink, manager said "sorry for the confusion, no charge, but no tables available... you can leave!"

Waiter was good, but manager did not care at all... disgusted... thank god it was my first time, it will certainly be my LAST!!!



Best Place To Eat On The River walk!!!

Always eat here when we come to San Antonio. Great food, prices and best hot sauce in town!



Really Nice View Ok Food

The view of the river walk was great and the outside dining we really enjoyed. The drinks were very expensive and the food was about a 5 out of 10. Just "ok" Mexican. Food.

Good food on the river

I was suprised at now good the food was and how affordable itwas. We were not gouged, like you expect at a tourist place. Food for four and GREAT margaritas for two came out to 50 bucks.

On the decline

I have always enjoyed eating at Casa Rio on the Riverwalk, but after our last experience, I'm not sure I want to go back anytime soon. The outside bar was closed the night we were there, so enjoying a margarita as we waited for our table wasn't an option.
Once we were seated, it took too long for a server to greet us. And, to make things worse, he didn't seem to speak or understand English. Needless to say, our order was very difficult to make and we felt that he never clearly understood what we wanted. When the food came, it was obvious that he had no idea what we wanted to eat.
We decided to just keep our plates because to attempt another order would have been too frustrating. It wouldn't have been so bad if the food we were served (but didn't order!) was good, but it was definitely below average.
Overall, the whole experience was a big disappointment. The only good part of the meal was being able to sit outside by the river on a nice night. Next time, we will choose a different place to do that.



baD servicE

We were seated indoors and all we could listen to were the staff members gossiping. Our server would forget that we were still there and it would take us a while to get noticed. The food was too salty and the rice was hard. I would not go back again. I though it was going to be a good restaurant.

Thoroughly enjoyable Mexican

There must be a reason that this place draws such a long wait and several other people who ate here earlier in the week recommended it to me. I decided to eat here on my last night while travelling for a conference and went around 9 p.m. so it wasn't as crowded and were seated promptly as a party of four.

Unfortunately, I wasn't very hungry so I only had the soft taco combo and split an order of chicken nachos which I enjoyed. Looking over the menu, their prices were very reasonable. They have a prime location on the river and seem to have the most waterfront tables which are in the shade of the setting sun.

I would definitely recommend this place to anyone and would visit again when back in the area. Allow some waiting time if you plan to eat during prime dinner time.

Having eaten at Casa Rio through the years and receiving excellent food, I am disappointed at their current state of operation. My wife and I were seated by the river and ordered a Taco Salad for her and a Chili Relleno (CR) for me. The CR was advertized to be deep fried. It wasn’t. It was covered with cheese and broiled enough to melt the cheese. The meat inside was lukewarm and not too tasty. Thinking it was just a fluke and had been sitting around; I had it replaced with a “fresh” one. It had a bit more cheese and melted more but was otherwise the same. Not in the mood for cold Mexican food, I questioned the waitress if they had anything hot. She recommended Fajitas so I accepted thinking it would be hard to mess them up since they are customarily served on a sizzling hot metal plate. Wrong again! The Fajitas came on a cold glass plate with the similar lukewarm meat and vegetables. The waitress, gun shy by now, deposited the plate and promptly disappeared.

My wife’s experience was no better. She generally does not complain about bad food, leaving that to me. However, the meat was the same lukewarm fajita meat I had with my order and the greens had the flavor of bagged lettuce. She knows the flavor well and will not use it for the family. She did not like it a bit. In addition, it was not served with the customary sauces and it took us four tries to get some to the table. Only after my Fajitas arrived and she was half way through her Taco Salad, did her sauce arrive

On the positive side, they still have a great, albeit expensive, Margarita Grande. And to their credit when I spilled a portion of it, they replaced it free of charge without us asking. The waitress tried to be accommodating with our meals but could only serve what was prepared.

All in all it was a bad experience in light of the excellent food we have received there in the past. Any restaurant can have a bad dish or a bad day and I usually overlook these. However, when they obviously keep food around in warmers and serve it as fresh, this is policy. It is how food is served at sporting events. I suppose with the captive audience on the River Walk they feel they can abandon their long standing traditions, comfortably rest on their laurels and become another tourist trap free from the rigors of turning out good hot fresh food consistently. I hope they turn around. It used to be a good place.
