Diner Reviews
  • "I took my daughter to lunch Saturday for her birthday. I was a bit concerned about dining on the rooftop in 90-degree heat, but I was pleasantly surprised that the misters kept things quite comfortable. The restaurant manager came by and we struck up a conversation. She was very pleasant. The waitstaff was very accommodating, and the meal was good. This was my first visit to The Rio, but not my daughter's. It was a pleasant experience."

  • "A super popular Boulder hangout, the Rio is the place to be on a perfect summer night. The rooftop patio is a hard place to get seated at when the weather is nice. Food is great, ambiance is hip, and the rooftop water misters keep the heat down. Even with reservations, be prepared to wait for the experience. The Rio is a great taste of Boulder in the summer!"

  • "We used the open table reservation that the Rio suggests. Friday Night at 5';30 for a party of 4. A Good idea to make reservations. We were located on the patio but not completely outside. The temperature was great, the food was good, service was ok and got worse as the place got busier. We had a great experience."

  • "We eat here often. Food is good Tex Mex and they have been expanding their menu. Moderate prices. Free chips and fresh salsa with options for other and hotter salsa."

  • "Everything was solid. They graciously accommodated our move to a bigger table so we could spread out, and the service was great. Minor bump when a margarita came out frozen instead of on the rocks, which they rectified with a smile. Food was very good, margaritas were STRONG, and tasty. Would definitely go back or try the other Denver locations."

  • "Of course, the marg's are the best in town but the food has had its ups and downs. The service and food were great! We had the crab and shrimp enchiladas; order them with green sauce, you will not be disappointed!"

  • "I came down from Denver to meet a friend who goes to CU boulder and I have to say it was quite an experience. The vibe was amazing around 10pm and it perfectly set the mood for the evening. Is definitely toe to toe with the denver RIO location. Thank you."

  • "I had heard good things about Rio Grande and was looking forward to having one of their margaritas. Our server brought our chips and salsa and the chips were broken bits, the size at the very bottom of a bag that you throw out. I had to ask her to replace them. My Big Tex margarita, for $8.00, was nothing special at all. I've had better. However, my Chili Relleno was one of the best I have ever had! I would return just to have another one - hopefully they are consistent. If you're looking for a Wow! Mexican Restaurant, this would not be that place."

  • "Drinks are great, food is poor, service is terrible. Roof top is also great. What can I say, I guess the margaritas and the view will bring us back but don't be in a hurry and eat before you go."

  • "The Rio Grande is a great place for Margarita's and people watching on the patio. The service was outstanding and the food was very good. We loved the home made tortillas and the fajita's were excellent. The jalapenos caps were very hot, so if you like a spicy hot appetizer than that is for you. We also had the home made guacamole which was very good. Great people, great food and a great place to enjoy fresh food, cold beer and a frozen margarita or 2."

  • "I've been eating at the Rio since it opened in Ft Collins. My family has probably been to the Boulder Rio more than 1,000 times: date nights, family groups small and large, birthdays, anniversaries, office Christmas parties, and when we just don't feel like cooking. Made lots of friends among the staff and other diners over the years. It's like home & family. Oh, and the food and drink are great! "

  • "The Rio is an institution. There are some staff that have been there for years and recognize patrons. The best house marg north of the Rio Bravo."

  • "We have dined here the past two times we have been in Boulder. We really like it! Had great service both times and the food is good and not overpriced. The margaritas are quite strong...there is a reason they limit you to 3! "

  • "Food was good and well prepared. Service was fine but the restaurant was quite busy and our server had tunnel vision when it came to her station. Noise level was extremely loud and not conducive to talking. The worst part though was the air conditioning. It was 45 degrees and raining outside yet they had their fans and air con on. These days it seems that many restaurants are more concerned with the comfort level of their employees than they are with their guests. All winter long we have dined in places with air conditioners running. I understand that the staff gets hot while running around but are restaurants open for the staff or customers? Take a tip: when most people in your establishment are wearing their coats, it means they're cold."

  • "I've been here a few times now. The margaritas are good and relatively strong. The food is very good - definitely above average and not too expensive. The outdoor seating on the roof is great when the weather is nice and has a nice view of the mountains. Staff is friendly and the atmosphere is lively without being over-noisy. Very nice experience."

  • "We frequent the Rio quite often and love them - they're one of our top favorites which is why we planned to have a birthday dinner here for my twin stepsons turning 20. The service was super slow this time (and we kept running out of water) and then in spite of calling ahead and letting them know about the birthdays (they do a little special something for bdays) they totally forgot about it :( This visit was just 'off' - an unfortunate thing for a bday celebration. We'll go back though because they're usually awesome."

  • "After living in the Boulder area for years I decided to check out The Rio based on numerous recommendations. I was so disappointed! I have had great margaritas with fresh lime juice, no mix and great tequila and The Rio margarita just wasn't 'it'. All you could taste was tequila and if that's what is considered a "great" margarita well I disagree. The salsa tasted like pureed tomatoes, no spice or flavor and the chips were stale. My steak tacos were bland and don't get me started on the rice and beans. Again, flavorless. It was one of the few times I could not wait for dinner to be over. Disappointed and really wanted to love having a good margarita place with good food locally instead of having to wait to fly to AZ to get it."

  • "The Rio is differently one of our favorite spots to go for birthdays or other events. they are so accomodating with taking reservations for our big groups and having the table ready and set to go when we arrive. Our waitress this time was spot on with no mistakes and always being there to refresh our salsas or drinks as needed."

  • "I brought my wife and 8 year old son for dinner here. Food was very good and the service was good as well. Kids menu had a nice selection and the margaritas were outstanding. We will for sure go back again."

  • "We have been to the Rio many times over the years. Our last two visits were a disappointment. The food was only okay. This time we noticed that our glasses were 3/4 full of ice when we finished our margaritas, so we suspect they are trying to cut corners by serving less drink and more ice. One thing we were always able to count on at the Rio was a really good margarita. There are lots of choices for Mexican food in Boulder now, so I'm not sure we'll be back."

  • "Rio Grande was somewhere my girlfriend and I had never gone before. We decided on this place because we both like Mexican food, and the food was great! She got a tostada and I got a smothered burrito. The best part of it all was that they were very accommodating to my Gluten Free diet and they even had a special paragraph in their menu about it. It is nice to see the awareness some restaurants have about food allergies. I really appreciated it! The only thing was that it was quite loud. I didn't realize the type of energy that was going to be at this place. Since it was Valentines Day and our Anniversary, I was expecting to go somewhere quieter. However, after getting used to the noise levels and energy, it still was a great date!"

  • "If you like noise, mediocre food, happening scene, rocket-speed dining, you should choose the Rio Grande Mexican Restaurant in Boulder. When ordering dinner, you can expect to get your food in 3 minutes. Then it's over. Table-turning is name of the game these days. Margaritas and food not extraordinary any more. If your goal is a Boulder "hot spot," this is it. Otherwise, there are many better places to eat and drink."

  • "3rd time I've been here. I loved how potent the margaritas use to be, but this time they seemed real tame...for the price, I want to feel that buzz!! I thought the portion size was just okay for the price and would like beans/rice with my entrée to make it go farther. I was still a bit hungry after my measly burrito. Still, I like this place and the food is good."
