This place gets a lot of inconsistent feedback, but I stand by their Chili Relleno. I have tried them all over town and have only gotten a hot, fresh, and crispy one at Rio Grande. They make great cocktails, and have a nice atmosphere and outdoor patio. I have only been twice, once in Boulder and once in Lone Tree. Boulder's service was lacking but not the Relleno. We had great service visiting the Lone Tree on a Sunday afternoon. Maybe we got lucky and it wasn't too busy. Overall we enjoyed the experience and I'll be back next time Im in the needing a Relleno fix. read more

Rio Grande Mexican Restaurant - Chili Relleno - Mexican Near Me - Lone Tree, Colorado

Probably the worst Mexican restaurant in Colorado. We were greeted by a young red-haired hostess at the front, and unfortunately she seemed completely uninterested in her job or even seating us. It was a very poor first impression. After being seated, things didn't improve much. The staff working the bar and nearby tables were very short with us from the beginning and gave off the impression that they didn't want to be there. What made it worse was that the restaurant wasn't even busy at all. I ordered a michelada, and honestly it was one of the worst I've had. I've tried micheladas all over the Americas, and this one was terrible. I specifically asked for it to not be too spicy, was told "okay," and it still came out extremely spicy. I couldn't even drink it. For food, I ordered a burrito while my friend ordered fajitas and a quesadilla. The pictures looked great, but the food arrived cold. We had also ordered well before the two tables next to us, yet they received their meals at least 10 minutes before we did. The only positive part of the experience was the woman who brought our food out from the kitchen. She was very kind and welcoming, and honestly the best part of the restaurant. Back staff should probably be taking the orders. After our food arrived, nobody checked on us even once. We were never asked if the food was okay, if we wanted another drink, or if we needed water refills. The server only came back when it was time to pay. Walked by us multiple times and never took the time to stop to ask us how we doing. There was essentially no service throughout the meal. I will say the decor and atmosphere were beautiful. The restaurant did feel like a small piece of Mexico, which I appreciated. However, as a Latino, the hospitality and service did not reflect the warm and welcoming Latino vibe I expected. Overall: great decor, but the service and food were extremely disappointing. There are many other Mexican restaurants nearby offering much better experiences. This place seriously needs to improve its hospitality and customer service. read more

OMG, this is my go-to for Chili Rellenos. NOBODY does it better. My wife was there for lunch and knowing I loved their Rellenos brought home a to-go order. Happy Camper here! They take a Serrano Pepper, fill it with cheese and yumminess, dip it in batter and deep fry it ... perfection. It's the ONLY way to make Rellenos ... THE ONLY WAY! I love it so!!! read more

Great Margaritas and many many GF options! The staff is friendly and professional. We slot the GF quesadilla appetizer and couldn't eat the whole thing! Great prices as well. read more

Happy Hour is $8 margaritas containing Three (3) shots tequila. Not bad. Free chips and salsa. Atmosphere is comfortable, but music, if any, was forgettable. Service was great! Perfectly attentive, quickly reloading glasses for hours, unobtrusively attending to guests that wanted to chat. read more

FOOD: Save your money. Awful food. Ordered big tex platter came on 2 plates super small servings and they actually forgot the ribs on the plates. How is that possible. Couldnt have been the first platter ever ordered. The table water tasted fishy, gross. First and last time coming here! SERVICE: the server was attentive. AMBIANCE: Other than swatting a fly constantly. It was enjoyable. read more

On 9/21 my sister and I met for lunch. The service was fantastic by Justin Caskey. The food and margaritas were also splendid. When we left Justin even opened the door for us. Thank you for the fantastic service. We will definitely return!!! read more

The service was good and the outdoor patio is nice. Their strong suit is their margaritas, they do not skimp on tequila. But the food is average at best. The Fajitas had literally 2 slices of peppers and the shrimp was a little dry. The rice however was surprisingly good. Their salsa is good too. So not bad overall, I'd come back for drinks and a snack on the patio. Also, they have many gluten free options that are clearly marked on the menu read more

Let's start with the salsa. Excellent taste and has lots of tomato rather than watery chili pepper. They have great Bloody Mary's. I ordered mine without the bacon strip. Bacon in a Bloody Mary? The huevos rancheros also were very good. I altered the order with black beans, no potatoes, and soft corn tortillas. Service was good and interior was modern and clean. I'm coming back. Wait, I have come back several times. read more

We went last night for a work dinner and I think it was just okay. We got there in time for happy hour and we enjoyed the queso. We ordered the jalapeño caps and they were cooked with the seeds in which made them SPICY! - I definitely thought they would be more jalapeño popper type but nope it was literally fried jalapeños. I had the strawberry marg mocktail which was delicious. It was just like the real version except without alcohol. I enjoyed their selection of mocktails. I had the shrimp and crab enchiladas. There was a generous portion of cheese that felt like too much. It definitely had shrimp but I did not notice any crab. My co worker had the relleno and said it was delicious. Our server was quiet and awkward and we basically could not hear him. He was too soft spoken to be a server read more

My husband and I just left the Rio Grande in Lone tree and we were super happy. We enjoyed celebrating their 40th anniversary with $5 margaritas and $10 burritos. We have a special love for the Rio Grande and tonight was just like a date from way back when... read more

Man this place has changed so much since I worked here back in 2004. I mean to see the restaurant cut in half and the kitchen moved was definitely odd, it's like the couldn't afford the other half of the building haha. So much character to this place though, service wasn't bad but I mean we came at lunch during the week. Chips an salsa never disappoints here. Don't get me wrong it's a decent place to eat but it was better back in the day. read more

Rio Grande Mexican Restaurant - Lunch combo of chicken quesadilla with salad - Mexican Near Me - Lone Tree, Colorado

The good: excellent service, good guacamole, good margaritas (silver coin) and tasty fajitas. The bad: the fajitas were barely lukewarm. Just about every other TexMex restaurant in America manages to serve sizzling fajitas -- this was pathetic. And the chocolate ice cream is full of grit (maybe this is ground up cacao bens, but a very poor judgment call) and has only a faint chocolate flavor. read more

Very mid chips and queso. Margaritas are good. Not a bad experience, just wouldn't necessarily recommend. Definitely better places to go.

The best strawberry margarita in town! I got both the regular and the strawberry and the strawberry by heart is the best. I got the nachos, completely delicious. And I appreciated the way they laid out the chips flat, so that all of the toppings could be divided amongst the chips. read more

The place seems very clean, there service was nice and food smelled amazing not sure about the flavor but it looks good

They were just like I remembered from when they were downtown! With two exceptoons.. the margaritas were famous downtown, they were just ok here and pricy. The queso was just ok also. The 4 meals were great. the chicken tostada, Baja tacos. Steak burrito and steak enchilidas were on point. read more

I don't live in Denver anymore but every time I come home to visit, Rio is a MUST! Sebastian is a phenomenal server! He goes above and beyond, anticipating needs, and makes sure to provide the best possible experience! The drinks and food are wonderful! If you haven't been here, you have to try it! Highly recommend! read more

Okay, the food is NOT great. The happy hour quesadilla was tiny, barely stuffed, and toasted rather than griddled. The jalapeño coins had a little bite, but the cornmeal breading was meh. The nachos were sad. My margarita was mostly ice. Literally about 4-5 sips of the drink, I think. Very disappointing. Not a fan of ice loaded over the top of the glass. BUT...the service is great, very friendly, and the atmosphere is fun. I've eaten here before. It's not GOOD Mexican food, but it's not "Old Casa Bonita" BAD, either. It's mostly meh. I do have a friend who eats brunch here EVERY Sunday. I have a standing invitation to join him. Maybe I should. It's possible that the brunch food is better than the happy hour food. read more

Place is really nice and clean on the inside! The lunch special seemed like a really good deal until the tacos came out and they were tiny with almost no filling. Food was mediocre. Salsa, however was YUMMY and the chips came out warm! Would be back if someone invites me but won't be going out of my way read more

Well, this used to be one of our favorite restaurants. We have been there three times over the past few months and today was not very good. Our rice and beans came out so cold fresh out of the refrigerator. Our fajitas were lukewarm. They did seem shortstaffed very disappointed in what used to be. However, the manager did come our fajitas half. read more

Queso del Mare is melted cheese(not proper queso). Perry Grande margarita is a shot of tequila & Grand Marnier , totally overpriced. And watered down lemonade. I would not recommend:( read more

Overall, I had a great experience at this place. They served chips & mild salsa once I'm seated in. I requested them to bring a hot salsa. Their hot salsa was too good. I decided to try one of their Lunch specials. (Taco combo) Pan seared Mahi Mahi, Beer braised Carnitas and Grilled salsa shrimp. All three were decent. I liked their tortilla too. Once you go inside the restaurant, you'll know how much bigger it is. read more

This restaurant is much larger inside than it looks from the outside. My family ended up here because the two other places we usually go in the area had closed. Overall the food wasn't bad, but wasn't good. The enchiladas were lacking seasoning and the chile rellenos barely had any cheese in them (or seasoning). My kids got nachos which was a small plate of chips with some cheese melted on it. read more

Everything needs approving here. We used to go to this place every Friday. But today the service is lazy and slow. The food under seasoned and light on any protein that you order. The Guacamole needs seasoning, spice and lime. So bland. Too bad this one won't last much longer. The people in LT are too smart. read more

Came in for lunch with my husband and daughter. The restaurant seemed short staffed. The waiter was pleasant. He was doing his best to wait tables and bar tend.

Tried again to see if it was just me. Service is still terrible even with a different waiter. Margs are good. Food is 7/10. Would much prefer other Mexican restaurants but their wait is over an hour. Next time I think I'll wait the hour just to avoid this place. read more

Rio Grande Mexican Restaurant is a TexMex staple in Colorado. I have been going here since I was a little girl and have loved this restaurant since; the difference is now I get to imbibe in their famous margaritas! We dined here for a double date at the Rio location in Lone Tree & had the best time. We arrived at Rio and were seated in a booth by the bar. The restaurant was lively as patrons enjoyed generous plates of classic Mexican fare & margaritas. The restaurant staff were awesome. Tequila Ambassador Jeff, General Manager Michelle, and server Tyler took great care of us. Jeff has been with Rio for 20+ years which speaks volumes to Rio caring for their employees & treating them like family. The restaurant clearly invests in their staff which translates into amazing service. I started off our meal with The Classic Rio Marg made with a legendary mixture of tequila, salt and lime on the rocks. Nothing beats a Classic Rio Marg (this got me buzzing). Each sip was fresh and crisp with the tequila balancing out the acidity of lime juice perfectly. The Rio carries over 80 different tequilas; all hand-selected and tested by Jeff & Rio's leadership team. We were able to try the Clase Azul Mezcal made in Durango Mexico. This Mezcal was one of the best I've ever had; it was extremely smooth and had an all encompassing earthy & smoky aftertaste that sexily lingered on the tongue. Brooke had the Agave Martini made with Don Julio reposado, grand marnier, orange liqueur, fresh citrus, and green olive. This cocktail had a sweet start followed by citrus notes. For Appetizers we had the Chile Con Queso and the Diabla Shrimp Empanadas. The Chile Con Queso was made with a cheese blend and pico de gallo. This is my favorite queso in town. The TexMex dip was silky smooth with perfect cheesy taste. The Diabla Shrimp Empanadas were made with sautéed shrimp, chile de árbol sauce, and jack cheese. The shrimp had firecracker spice and chew in that texture paired well with the crisp fried exterior of the empanada. We got to try one of the new special menu items - the Mexican City Chicken Tacos. The spicy, crispy fried chicken topped a bed of bright slaw and was drizzled with hot honey. Brooke had the grilled Steak Fajitas served with rice, black beans, grilled veggies, guacamole, sour cream, pico de gallo, and flour tortillas. The steak was covered in rich marinade prior to grilling making it flavorful. The meat was tender and juicy and paired beautifully with the bright medley of grilled veggies. Ross had the Rio Classic Chile Rellenos made with in-house roasted green chiles stuffed w/ cheese & sautéed veggies, and lightly fried. The roasted poblano pepper had a crisp, fried exterior that gave way to the soft vegetable stuffed with melty cheese. I had the Crab & Shrimp Enchiladas made with Atlantic red crab, shrimp, jack, and tomatillo sauce. The corn tortillas were generously filled with sweet shrimp and crab and coated in savory sauce. Marcus had the Tacos A La Carte and had 1 Baja Fish taco, 1 Steak taco and 1 Cilantro-Lime Grilled Chicken Taco. The Baja Fish taco was made with Haddock, tortilla, cabbage, and a Mexican-style crema, Valentina™ hot sauce. For dessert we had the Crispy Sopapilla made with tortilla dough, cinnamon, and sugar. The homemade sopapillas were thoroughly coated in cinnamon sugar making for sweet bites. The fried, puffed dough was flakey and soft and stood out with a drizzle of honey. read more

12 bucks for a little shallow bowl of velvita they called queso. They're scamming here. Go here if you got money to blow on some bs with mid ingredients. 16 bones for 3 "street" tacos is crazy. You can make 20 street tacos for the same price, it would taste better, and take the same amount of time. read more

I frequent the rio, so obviously I have a lot of good things to say! The service here is always good. Hostesses are polite, and servers are always attentive. I change up my food order frequently, but consistently get the strawberry margaritas. Their margaritas are delicious and strong! I can't say I've had any disappointing food or experience here. The restaurant is spacious and has an upstairs portion as well, which I love. I definitely recommend stopping here if you haven't! read more

Used to go to the one Downtown, but I can't stand going into Denver anymore, so we tried the one in Lone Tree. The salsa was excellent, we had the beef/chicken fajitas for 2, and should have went with just beef because it was so tender and good. Service was great, we went on a Saturday around noon, so it was not very crowded. Will definitely go again. read more

It was nearly $150 for an appetizer of queso, 2 fajita orders, and 4 drinks. Additionally, I didn't appreciate seeing a 5% service surcharge on top of 20% gratuity. I really dislike eating in this post-COVID world. Service was decent but it's not really a good business practice. Restaurants should just adjust the price of their food accordingly. Overall the food didn't have much flavor and drinks were just ok too. Nothing wowed me about any of the items. read more

Have not been here in many years. Was a little disappointed the hostess was not friendly at all felt like we were inconveniencing her. We sat in the bar, great spot with a fun biz of other diners, clean and comfy. Our waiter was amazing! We had drinks, fish tacos, hubs, they were just ok. We had the tortilla soup great flavor BUT SOOOO salty. We shared a guac now that needed salt. If you don't know they have other salsas beside the plain red they bring out, we love the atomic a but spicy but yum. I had the the steak tostada, the steak was cooked perfect, delicious. Big so you need to use a fork kinda like a black bean salad with steak and guac on top of a tostada. read more

Rio Grande Mexican Restaurant - Steak tostada - Mexican Near Me - Lone Tree, Colorado

Service was great, price was reasonable, food was very good. The reason for the 4 stars and not 5 is because; if I may suggest to the chef, always, throw the corn/flour tortilla on the grill for 30 seconds. Grilling it makes it taste better and most importantly, it will hold up better in a taco. The Tacos were wrapped with a corn tortilla straight out of the bag, cold and flimsy. By the time I got to my third taco, I picked it up and the tortilla was soggy and could not hold the taco together. It's a simple extra process, but it's so much better. read more

Expensive for what we received. We ordered the surf and turf fajitas ($45) for 2 after being reassured it would be enough for 2 people.

We will not go back and will not recommend to others. read more
