Casa Rio

I always make a point to come here when I'm in SA. The food is always great. I will say the huge margarita was more gimmicky than anything; pretty light on taste for 25 dollars.

Clearly if it's busy (like it always is on the Riverwalk it can get cray cray, be nice to the waitstaff ) food is good. Crispy tacos are really big and first round of chips is free .75 after for each 1

Great food,atmosphere,& staff !Go when it's nice out and enjoy the experience. Beware of the pigeons and ducks that want your food.I highly recommend this place...especially if you're from out of town !

Enjoyed the Tacco Salad with chicken and shrimp . The view is great and you can see boats come by as part of the scene. The offer photos and live personal music at your table. Great experience ????????

Green enchiladas were full of flavor. Not spicy at all. They are huge, two is more than enough. Sit by the river to enjoy the view .

Loved our waitress , Virginia! I had Chicken Flauta Dinner . It was great! Atmosphere good, scenery on the River Walk was good, ducks greeted us for dinner . Loved it!

Absolutely the best traditional Mexican food I've had in a long time. Wish I was a local. Outstanding and inexpensive .

The Casa Rio is a superb Mexican restaurant ! It is always a treat. try the regular plate, which has samplings of lots of different good things.

Amazing Mexican food and extremely pleasant ambience by the river walk . Will miss the tex-mex salsa and guacamole back home, it's so different from the Mexican food back there.

A very special old Tex-Mex restaurant . The combination plates are amazingly good!

In the River walk, great view and very good service , delicious margaritas and very good quesadillas

The street tacos and rice were amazing! The mariachi bands make a really cool atmosphere as well !

Staff was welcoming, service was quick, food was good, sitting along the River Walk was nice.

Fajita plate is not grilled strips of meat - but grilled meat cut into strips. chicken is horrible, but the steak is tasty. The salsa is pretty good - actually spicy . Overall not real Mexican food .

History and huge plates that taste above average ! I have been here numerous times and we usually take visitors to San Antonio here.

As a margarita fan, I enjoyed mine a lot and the chili on a cold night outside hit the spot. Good price too.

Muchas Gracias Beto!!! The enchiladas/tacos are delicious!!!!

The chips and salsa were really good! Margarita not bad. A lot of food for your buck!!

The chicken enchilladas are the bomb !! And also the nacho speacialty !! Cheap , delicious & great service !!

Carnitas were great once again. Guacamole and pico de gallo rounded out a great meal!

Great salsa and authentic TexMex for the Riverwalk. Go down to Mi Tierra or La Margarita for the real thing.

I'd come back just for the amazingly good fresh salsa , but everything else is delicious too! Definitely on the do-again list! <3

Eating inside the restaurant can get a little noisy . If the weather is good eating outside is much better.

go for the peach margarita and even if the wait is long ask for an outside table .

When you get a marg get an extra shot to go in it, makes it the best

Charo beans and chili relleno were surprisingly good. Reasonably priced as well .

Oldest family run restaurant on the river ! Buy local !! The chains are taking over

1st Restaurant I ate at here in San Antonio. Great Food ! Loved their local Alamo Beer

Had a blast feeding the ducks n fish on the river . The cheese enchilada was tasty!

Can't go wrong with the enchiladas late ????

Love the place, loved their food and service.

Great restaurant with decent prices on the River Walk!

Enjoyed the sangria swirl margarita .

Lots of food for great prices. Try the Chili con Carne !

I've been coming here since I was 2 (over 35 yrs) and never disappointed

Locals know the story here. Keep moving along and hit Pierdas Negras. Tourist , not a bad spot at all if your visiting. Enjoy the riverwalk!!

Great atmosphere surrounding the restaurant ! Chicken fajitas were delicious!

Nice atmosphere. Can dine on the Riverwalk or inside.

Food is excellent! (Much better than Mi Tierra)

Had a great meal and the ambiance was spactacular

When ordering the soft taco , make sure you ask for shredded cheese if you want cheese .

The chicken flautas were great

Three words: ground beef tacos . Yeah, fantastic ambience and mariachis. The food is however, abysmal.

Had the green chicken enchilada and it was pretty yummy.

If you love mixed drinks , you'll enjoy here. Minus the drinks...the foods alright. Still worth a try imo.

Chili con carne , BIG chunks of BEEF steak ! Get it, this is man food!

El Rio was great ...highly recommended!

Great flauta plate, get it with some queso and you'll leave a happy person.

Great views , mediocre food, slow and below par service. Still worth a visit… Or pick one of dozens of alternatives nearby.

We had an awesome meal here with truly wonderful service. Highly recommend.
