This was my first time trying barbacoa so I can't speak to authenticity, but this is hands down the most flavorful taco I've ever had in the Denver Metro area. The beef is so tender and bursting with rich flavor. Their red salsa was perfectly balanced, striking that ideal balance of savory, spicy, and acidic complimented the beef perfectly. The only thing I could think of that would have pushed this over the top is better tortillas. Hard to knock them though for that when that is the standard in Denver unless you want to overpay for a taco. I highly recommend this food truck if you want a real Mexican street style taco, keeping in mind that this is strictly a food truck so there is no ambiance or even a place to eat them, strictly to go or eat in your car. The service was prompt and friendly. read more
