Great food, prices, and patios! Yes, they have 2 options!

The strawberry rocks margaritas and chicken fajitas are absolutely AMAZING!

Food was great, although the chips didn't seem as fresh as others I've had. loved the fish taco and coconut flan! Hard to compare noise level with normal, since there was lots of space between tables.

Love the Rio

Come to this restaurant for years and driven pretty far to reach it. Love food and margs.

The service by Travis was excellent. We were there celebrating my daughter's 21st birthday and it turned out to be a very enjoyable evening. My thanks to the Rio staff.

We always enjoy going to the Rio. The mars are great! Service is a bit slow. Had to wait a while for my second drink and for the check. Otherwise, the food was wonderful.

Very good food. We had a great table on the patio andf the staff was friendly and attentive. We really enjoyed the evening

Server was friendly and attentive. The ordering system went down when we were getting ready to leave. We had to wait for a little bit (which was fine). He checked in with us regularly and eventually they had to manually check us out using carbon copy credit slips. He felt bad for making us wait- but I have worked somewhere where that happened. I think he handled it well and made sure we were OK. Food was delicious as always- best salsa ever!

Food was fresh and delicious! Drinks great as always.

Rio continues to provide outstanding customer service, super friendly servers (prefer to call them friends as we know almost all of them!), food, and drinks. Thank you for managing to keep the restaurant open and safe.

Always have had great service and food at the Rio in Lone Tree.

We go to the Rio every weekend. The service is almost always spectacular and the food is great. The margs are out of this world. We have been going to the Rio for the past 17 years!

Specifically made a reservation for the outside patio & confirmed this before arriving. When we got there, we were told they were no longer seating on the patio due to weather. Which would have been understandable if the patio was uncovered, which is wasn’t. And there were 4 full tables seated out there currently anyways. We were willing to sit outside despite the weather but were repeatedly told no for various fleeting reasons. I understand that this pandemic has caused a huge adjustment in how restaurants operate but they could also strive to be flexible with guests who do not feel comfortable sitting inside.

Wonderful as always. We miss the Frisco location, but when in Denver we always stop here.

I absolutely love their guacamole tostada and my husbands favorite is the Chile Relleno.

The food was good, service was good, I do miss not having ground beef as an option.

The reservation process was so smooth. We showed up and immediately shown to our table, even though there was a wait. Our server was amazing and attentive. Overall a wonderful experience.

Our order was wrong and it was not adjusted in the bill. Very over priced and just not the same quality as the Denver or Boulder locations.

Received a gift card and was excited to try out Rio Grande in the Lonetree location. Ordered chicken fajitas and 3 tacos. All food was served just barely warm and did not taste like it was prepared fresh. Very disappointing- especially considering the price point. We were glad that we had a gift card to use and considered it a “free meal”.

Very clean especially with all the new Covid-19 rules. Food was delicious and came out fast. Margaritas are always amazing as well.

This wawas the best meal I have ever had at the Rio! It was so much fun to go out again. The only thing that wasn't their fault was the wind. We sat in the outside. They had blinds down but they banged quite loudly. And often. I would have asked to be moved, but I didn't want to cause a problem. They were so nice.

Great as usual

Food was good but drinks were slow to arrive

The service was great. The food and margs were lousy. Will not be retuning.

Was a good night as always at the RIO

Came in and was seated right away despite many others waiting.

When seating a table of 4, please place 4 water glasses, not just 2. Our server took 2 away, when clearly there were 4 of us. Food value was ok

The food was not as good as usual. It’s a fun place but I’d like to see more focus on the food - even during busy times.

Great meal for us and our kids!

Went for Valentines Day. Place was understaffed. Service slow, terrible. Margarita was good. Food average to below average

We received the receipt which was correct. When I got the credit card slip I was charged a different amount by several dollars. Lucky for me I remembered the first amount and questioned the credit card invoice.

It was delicious and the drinks were good too!!

Great service, food and margs ! Our favorite place for Chile Rellenos !

Garret the sever was amazing

Try it, you’ll love it! Good and service were great!

Food are consistently really good! Love that it is local and has been good for so long.

I love that Rio Grande takes reservations as so many restaurants in Highlands Ranch do not. We were seated right at reservation time and had a great evening with friends.

Chris and Rob took great care of us on a 'super' busy night. The food, margs, and service was great...as usual.

Our server would check in very rarely- we got our food but didn’t have silverware, and it took almost 10 minutes to get a hold of her and by that time all our food was cold. Soup was inedible- so salty and awful. Margaritas and atmosphere are good but we definitely won’t be back
