out of 5 starsCheap and quality Margs! by MikeWils on 10/28/2011 via Citysearch
I have heard about Rio Grande but for some reason I have never been in. They have pretty good Mexican food, but the best part is their Margaritas. They're really tasty and completely affordable. It's not a fancy sit down restaurant, it's…
Techno club for students by Snowbunnymaui on 6/22/2011 via Citysearch
It was 7ish and the techno music was so loud I couldn't even hear the waiter. The food was AWFUL and the service was very bad. I think this place is great for college students who want to get wasted and party, as the bartender was clearly…
Go for the atmosphere by ValVista on 3/15/2011 via Citysearch
Plan to have a couple of margs and see & be seen, then go somewhere else for dinner. Very bland food.
Decent for a Tex Mex place in Boulder by Rhialistic on 4/30/2010 via Citysearch
First of all, this is Tex Mex, not Mexican. This should be considered when reviewing the food. It will not be "authentic" and will be seasoned much differently! That being said, I've been here several times and have NEVER had anything…
Terrible, Bland Food by misskimberly on 2/5/2009 via Citysearch
TERRIBLE, bland food; I cant even eat it when Im drunk.\r \r The margaritas are good, however...but dont even bother with an appetizer at this joint.
Still the Original by Rajeev M on 12/27/2008 via Insider Pages
Located right near Pearl Street, the Rio is a favorite among the locals. The margaritas are great and the food is excellent. It can often be packed and have long waiting times, but it is well worth the wait.
A Boulder Classic by IanB1413 on 10/21/2008 via Citysearch
OK, so there's alot of differing opinions about the Rio. The truth- it is one of the best places in Boulder. Nowhere else can u go for the atmosphere, overall food quality and delicious margarita. As a long time regular I'm going to lay…
Great Margs and Nachos! by LizWhite2 on 7/19/2008 via Citysearch
I've been here numerous times and have yet to have a bad experience. There margs are tasty, if you like them strong. Being a vegetarian I love the fajitas and nachos. Granted it's not the best mexican food out there, but it's got average…
Great mexican by Sarah P on 5/16/2008 via Insider Pages
I really enjoy the food here, though I think the margaritas are a bit overrated. They put extra shots in them so it'll put over the top faster than normal.
Chicken Bone in Enchilada by caitlisbeth on 5/8/2008 via Citysearch
The margaritas are definitely worth going there, but the food is a different story. I refuse to eat there since I found a 3 in. chicken bone in my enchilada. Go for a margarita and chips and salsa, anything more than that is a gamble.
Great Food, Amazine Margs and Cool Staff by Safarigirl on 4/29/2008 via Citysearch
This place ROCKS! Literally, the margs are the best and the food is amazing. Their food is fresh and they don't use any lard in any recipe. Their salsa is heavenly and when you sit on the rooftop, sip a marg and eat a healthy Salad,…
Centro is the place to go, NOT RIO by alicevans on 4/13/2008 via Citysearch
If you think that Azteca is actually good Mexican food, than you might like this place. Otherwise, if you own a tongue, please stay way. Cheap margaritas are ok, but if you want real good Latin food, check out Centro or Tahona Tequila Bar.
Margaritas, of course. by abd1350 on 2/20/2008 via Citysearch
I am not from Boulder and was taken here by my friend and wow. I am now Rio obsessed. Their margaritas really are as amazing as they and everyone else says, and the food was fantastic. It's a really fun place to eat and get ridiculous,…
The 'LAST PLACE' in Boulder to eat by man_in_boulder on 10/19/2007 via Citysearch
Unfortunately, I have eaten at the Rio Grande Mexican Restaurant 3 times. Each time was worse than the last. I don't know how it stays in business. On my second and third visits I tried to convince my friends to choose another restaurant…
I am so sorry, this review was meant for Centro on Pearl Street. by tkm303 on 9/20/2007 via Citysearch
I don't ever do this and I created an account just to write this review. I would have to say this was the worst meal I have ever had. The service from the waitstaff was good but the manager was far from it. My visit here a year ago was an…
Poor management and service by radhikapradhan on 9/15/2007 via Citysearch
Had an awful experience on Sep 15th . We chose rooftop seating as the day was nice but the service was beyond poor. We waited for 20 minutes in the hot sun and finally had to flag a server to get us water. The hostess did ask the couple of…
Terrible service, good salsa by kristylsummers on 6/24/2007 via Citysearch
The Rio has really gone down hill. Today, in for a late lunch, the server, while nice, brought out soup (appetizer) with the actual entrees. The Rio is notorious for bad timing. The green chili (which I ordered the regular kind, not the…
Margaritas by reniour on 11/13/2006 via Citysearch
Margaritas, Sangrias, House Margarita, salted, surgar, iced, on the rocks. \r \r This place is where to go for margaritas. The food is average, getting better but you go to this place for the Margaritas. They have a 3 Margarita limit for a…
Average Mexican - Decent Margs by ambrosgela on 11/4/2006 via Citysearch
The Rio is hyped a little more than it is worth, still a good choice for a weekday lunch. Decent happy hour deals, service is inattentive and indifferent. Margaritas are okay, I've had better and worse - but they will sneak up on you,…
Great margaritas, OK food, mediocre service by jalmy on 7/23/2006 via Citysearch
I really enjoyed the margaritas! They aren't syrupy-sweet and they tasted great. I originally tried to order a different mixed drink, but our waiter claimed that they only have beer, wine, and tequila. The food was good, but nothing…
