Did you know that Rio has a scratch kitchen? Every dish is crafted with care—from sourcing the freshest ingredients to preparing them in-house.

Take our Chile Rellenos, for example. Prepared with a house-roasted Chile and the perfect blend of skill, pride, and love. No shortcuts, just brilliance in the basics!

Did you know our frozen margarita machines have a secret past? Back in '86, our owner, Pat McGaughran, got creative with a broken soft-serve ice cream machine, transforming it into Fort Collins' first-ever frozen margarita dispenser, which introduced the notorious Classic Rio Margarita!

Fun Fact: Did you know that Mezcal isn't traditionally served in shot glasses? Enter the Copita—a shallow clay cup that lets you savor every smoky note up close. It's not just a drink; it's an experience

Rio Grande is celebrating Harvest Fest! From now through September 1, guests can enjoy seasonal delights:

· Watermelon Margarita: A bright and refreshing margarita made with locally sourced watermelon ????

· Barbacoa Esquite Tacos: Melt-in-the-mouth, slowly braised beef barbacoa with a playful twist ????

· Elote: Mexican street corn featuring local Colorado corn

· Strawberries and Cream: A spin on the popular Mexican dessert Carlota ????

Craving a cool, summer sipper? Meet the Ranch Water – the Texan classic making waves nationwide. Topo Chico mineral water blended with blanco tequila, garnished with a salt rim and lime. Pure refreshment!

At The Rio, our team isn’t just a group of coworkers—we’re a family. Interested in joining the Rio team? We’re always on the hunt for good, smart, dedicated people to join our family. With some of our team members having 30+ years with us, it’s a place where careers grow, and people truly love what they do. ????

Every Thursday from 9- 11 PM, The Rio is your best pre-game spot in Fort Collins, Boulder, and Greeley. Grab your crew and let the good times roll! ????✨

HOLY (house-made and delicious) GUACAMOLE! ????????

Loaded with fresh pico, cilantro, and cotija—scoop it up with chips or crunchy veggies and thank us later. ????

That crisp Colorado fall air is finally here, and we’re soaking it up! ???? Join us on your favorite Rio patio to enjoy the season, good company, and great vibes. Cheers to fall!

It’s Happy Hour o’clock!
Swing by your favorite Rio Monday through Friday from 3 PM – 6 PM for $2 off Rio Classic & Big Tex Margaritas, $3 drafts and cans, $5 wine, and $1 off your favorite tacos. Cheers to the perfect end to your day!

Rio around the world! These incredible regulars have been with us since their first visit to the Fort Collins Rio in ’95. Now loyal Lone Tree patrons, they took the Rio spirit (and some friends!) all the way to Tromsø, Norway, capturing this fantastic shot in their Rio tees.
Thanks for sharing the Rio love across the globe! Have a pic of your own Rio adventures? Send it our way!

It’s soup season, amigos! Warm up your day with our famous, house-made Green Chile Soup. Made with fresh green chiles, sautéed chicken, and rich house-made chicken broth. Pair it with warm flour or corn tortillas, and you’ve got the ultimate cold-weather cure.

Shell or bowl?
Our tostadas got an upgrade! Stick with the crispy fried tortilla shell or go gluten-free with a rice-based bowl. Either way, you’re in for a treat with black beans, crisp lettuce, and juicy tomatoes. Which one’s calling your name?
