We were coming home from a long day of driving and found this place along the way. To say it is…read morethe best Mexican restaurant food I've ever had would be an understatement. Everything was epic. We started with chips and salsa and beer. I wish I could remember the name of the young man who served us because he was a very good bartender and server. I ordered three different tacos and man, oh man! The cauliflower taco was hands down the best taco I've ever eaten. The lengua taco was just as good. The seasoning and accompanying veggies were the perfect ingredients for these tacos. The Baja shrimp tacos were good too, but not off the charts like the other two. The street corn was seasoned nicely and I enjoyed each and every bite My husband, who doesn't really like or eat Mexican food ordered the Philly Steak and Cheese burrito with rice and beans. He ate all of it, so I know it had to be good. We are already making plans to return, although it's over an hour away from our house. I'm excited to try other items. Barrios, thank you for the great food, the clean bar, and the excellent food. We look forward to seeing you again! And, we were aware of the upcharge for using a credit card, so there were no surprises as mentioned in other reviews.

It's time to update my review from 2 years ago! Yes, Barrios, you have a dedicated fan now! Since…read moremy last review, lots has changed about this place and only in a good way! They added an outdoor, dog-friendly patio and a new bar inside. Each time I've come now, that place has been clean and inviting! The service has been great - prompt, attentive, and friendly. But as a taco-loving Texan who now resides in TN, I have to say this is the BEST Mexican food in town. They have the best salsa, margaritas, and everything I've ordered, from tacos to brunch items to green chili has been yummy! While the salsa has been toned down for the 'can't handle the heat' locals - just ask your server for something else with more spice. They will accommodate you. There's some salsa Verde and tomatillo salsa that has a bit more kick and is my go-to! And they have corn tortillas too - you can just ask them to swap them out for the flour if that is your preference. I promise, my partner and I have hit just about every Mexican place in OR - and he even agrees, Barrios is where it's at!

I REALLY want to try something else. But when I get in there and open the menu...it just happens. "Barria tacos and an unsweetened iced tea"... Over and over again. I just can't help myself. Trust me. They are worth the trip. Go give them a try.

Unfortunate as we much prefer to patronize a small mom & pop like this. Staff was friendly and service was rapid enough. Ambiance is cozy and made us hopeful.

While the food still could have been hotter, temperature-wise, I must say the chili rellaño tasted top-notch! La Casa De Burro Flojo serves the peppers stuffed with melty cheese in an egg-battered coating that's fried and covered with a mild red sauce. It's one of a few Knox-area eateries that "gets it right." To top it off, I could find no pithy seeds inside, as several Mexican restaurants fail to remove them. So I tip my hat to the cook!

I came to pick up my order and was greeted when I walked in. The employees were all very friendly. I got my order and when I opened it I thought, oh crap it looks hella hot. I didn't want to have them remake it. So, yea... it was fire going in... and out... It was freakin delicious though and great grilled flavor. I will definitely come back but make emphasis on Mild.
