The Rio is a great place to go for drinks on their rooftop patio. They have delicious complimentary chips and salsa. While their margaritas and appetizers are tasty, I would not recommend ordering from their weekend brunch menu. The huevos rancheros and the breakfast burrito were fine, but were quite basic. Honestly, I make better huevos and burritos at home (and I am not an impressive cook!)

Our server was great; she was prompt and attentive.....- The Hostess should have given us a larger table for 10 people- it was a bit crowded. otherwise it was fun, festive and very good food!

Yep...went there for Cinco de Mayo! We were seated (party of 4) within five minutes of our reservation. Staff, though pulled in many directions, was pleasant, attentive and helpful. Our waitress was engaging and pleasant. Good arrive promptly (despite what had to be a very busy kitchen). The food was well-presented and yummy. The braised pork tacos were especially good. Fun place, good food and helpful service. Yes, I will go there again!

Cheers.

We had a reservation, but we still ended up waiting about 25 mins to be seated. Waiter was slow, took forever to even get us water. We ordered guacamole and queso as appetizers, both were bland and we got “bottom of the bag” tortilla chips. Entrees were good. We had the steak fajitas, the steak burrito, smoked chicken tacos, braised pork tacos, shrimp tacos, and chicken enchilada. Everyone liked their entree. I’ve had better food and better service. Probably won’t return, as there are many other places in the area that have better food and faster service.

My husband and I have been going to the Rio for years frequenting a lot. The food is good we enjoy the atmosphere, love the margaritas however incredibly annoyed that we register for Open Table and almost always the hostess try’s to seat us at the worst table in the restaurant. It almost always happens and we have to refuse the table and ask to be seated at a different table. Feels very disrespectful that this continues to happen. Someone who makes a reservation at your restaurant should not be given the crappiest table in the restaurant. This is truly disappointing. It wouldn’t be a big deal if it only happened once but almost every time we make an open table we get offered a crappy table.

The service was good. Food not so much. It was highly recommend by several people and I wasn't impressed. The food was only so, so and the margaritas which everyone said we're the best they've ever had, were terrible! I don't normally leave bad reviews because people should make their own decisions, but I wanted to give at least give a heads up.

I have been to the Rio multiple times. The first several visits were an excellent time, from great service to great food.
However, I recently went there to celebrate the birthday of my significant other's mother, who loves Mexican food. I thought what better place to take her than my favorite downtown spot.
We went during saturday dinner rush, however I made a reservation in advance so seating was not terrible.
Unfortunately, for the first time since I have started coming to the Rio, the service was absolutely infuriating. The rough visit started with our seating host, who gave us cups with silverware in it and told us if we could handle taking care of that ourselves.
Our waitress, the culumative failure of the night proceeded to take over 10 minutes before coming by for the first time. It was busy, so I forgave that. The first time. But how incredibly long she would take to come back to us (10,15, 20 minutes of nothing but waiting on her) it was inexcusible. The first time, she apologized, took our drink orders and left.
Another age went by before she walked back with the wrong set of drinks, turned around and disappeared again. By this point we were starving and frustrated, almost reaching half an hour if not more.
She returned with the ordered drinks, spilling one of the margaritas all over a menu and didn't do a damn thing about it. Even waved the liquid off before walking away. We cleaned the mess ourselves, and my SO's mother saw her margarita, (of which I boasted the quality of) had absolutely no salt and barely any liquid since the waitress had spilled it. She told our ever disappearing waitress, who came back with an empty salted glass and left it for us to combine ourselves. After the previous events, it was just plain old rude at this point.
Several more minutes pass, and she finally takes our order before disappearing again. Another waitor had to assist us.
I don't know if I will be back any time soon.

Definitely get a reservation beforehand. We were seated right away and although the restaurant was crowded, loud, and a little chaotic our small double date group had a great time. Our margaritas were great, food arrived within 10mins of ordering, the food wasn't spectacular but very good, our server was very cheerful and attentive. Overall, we had a nice time and can't wait to sit out on the rooftop patio in the summer!

My family has been to the Rio Grande several times to celebrate birthdays. This was our worst experience and will probably not be returning. First, there was a problem locating our reservation. Then we asked for more chips which were never brought and two of the meals were wrong. The food wasn't as tasty as I remember it being. Since we live over 20 miles from the restaurant, it's unlikely that we'll be returning.

Thank you,

Taylor was our server and she did great. Chips and Salsa were on point. As was atomica salsa. Had enchiladas, one steak, one spinach. Were delicious. Walked out of there stuffed for a very reasonable price. Sat in the garage. New table tops looked great and tables are self leveling now, so no wobble. Great experience.

I really like this place, but had a disappointing experience two nights ago, mostly due to our female server. The server didn't take the order correctly, I ordered a 1/2 shrimp and 1/2 veggie fajitas--she place the order as shrimp with added vegetables (there is a difference in content and price). The fajitas were served without any of the accompanying garnishes---cheese, guac, pico, sour creme--which made for a rather uninspired meal. She didn't refill coffee nor salsa until asked. After the food was served (by others) she essentially stopped checking our table. The margaritas--manberry and agave--were great.

I love the Rio even more now that I know I can make a reservation. Been going for years. Love the food and especially the margaritas -- especially the mini ones! Awesome roof top dining, and lots of great indoor spaces as well. One of my top five places to dine in Boulder.

was crazy busy after the game last Saturday. We made a reservation and still had to wait a bit...not that big a deal. It was just so overcrowded it was claustrophobic. I can't imagine being a waiter and trying to get around like that. We tried to order more drinks to go with our dinner and never received. Think the bar was totally overwhelmed. The waiter was doing the best he could with the situation. I think bar orders for diners should be a priority.

The food is just ok. Not bad, but not great, either. The service is always friendly, but it always seems to be a bit of a chore to get the correct and complete order. Whether it's forgetting a drink, an extra side of sour cream, or enough chips for the table, it just never seems to be right the first time. Net-net, not a bad experience, but not great.

We had a group of 8 people.
Our food was cold!!!! My fajitas were not even grilling when they brought it to my table!! Same story with my friends food.. her chips for the nachos were burnt and she couldn't eat it. We asked the waitress to bring us a well done meat and the attitude was just not the best. We even told him in the end of the night how frustrated it was to pay almost 200 for burnt food
I will NOT COME HERE AGAIN!

Service was good, but the other aspects of the meal were underwhelming.

Service: Our server Katie was terrific -- friendly, helpful, knowledgeable.

Drinks: I used to love the classic Rio marg, but this time it just tasted of citric acid (think lemonade powder). The Agave Martini was better, if a little strange. My husband ordered red wine. They only have two on the menu, and they were out of one of them (how does that even happen?!).

Food: The Queso was bland. My spinach enchiladas were fine, nothing to write home about. The burrito had very little chicken and the "fajita vegetables " inside were still crunchy, not having been grilled enough to even cook through.

Bottom line: We won't be coming back any time soon.
