Blue Corn Tacos isn’t the kind of place you stumble upon by accident—it’s the spot you hear about from someone who knows food. Nestled at 1515 Main St Unit #5 in Longmont, CO, this unassuming gem serves up bold, borderless Mexican flavors that hit different. From the outside, it might look like just another neighborhood taqueria, but open the door and you’re immediately wrapped in the aroma of roasted chiles, sizzling meats, and something subtly smoky that can only come from house-made corn tortillas grilled to perfection.
The menu is refreshingly straightforward but packed with personality. Each taco is built on a handcrafted blue corn tortilla—soft, slightly chewy, and earthy, giving each bite a depth you don’t usually expect. The carnitas are slow-braised and crispy-edged, while the al pastor bursts with pineapple-tang and achiote warmth. If you’re into seafood, the grilled shrimp taco with citrus slaw is clean, punchy, and impossible to eat just one. The vegetarians aren’t left out either—the rajas con crema taco with poblano peppers and queso fresco is a sleeper hit. Every ingredient feels like it was chosen for flavor, not just to fill space.
We visited on a weekday around 1 PM, and the place was already buzzing. Locals know this isn’t fast food—it’s real food made fast. The kitchen is open, the staff greets you with confidence, and you can watch tortillas puff up on the comal while your order’s being plated. Their aguas frescas rotate often—on our visit, the hibiscus was tart and floral, a perfect match for the rich, fatty tacos.
What stands out beyond the food is the vibe. This isn’t a spot trying to be trendy. There are no gimmicks, no Instagram walls. Just good tacos, warm service, and an honest focus on quality. On review platforms, they’ve built a reputation for consistency, which isn't easy in the taco game. Multiple reviewers highlight how the tortillas are made fresh daily, and you can taste that labor in every bite. That attention to detail? It’s what keeps people coming back.
As for location, it’s convenient whether you’re passing through Longmont or making a dedicated trip. Street parking is easy, and if you're lucky, you’ll catch a table on their small patio out front. There’s a rhythm here—people ordering confidently, chatting about their go-to picks, debating between the green salsa or the fiery red. (Pro tip: get both.) The kitchen staff doesn’t just cook, they craft. And when a plate of tacos lands on your table—neatly arranged, garnished just right—you get the sense they care about the final result.
In a town where tacos are serious business, Blue Corn Tacos manages to stand out not with flash, but with focus. From their distinctive masa to the punch of their salsas, every element connects. It’s not trying to reinvent Mexican street food—it’s honoring it, thoughtfully.
“ Strait up the best Mexican food in northern Colorado. Quality is always the same and the food is always hot. I hope the place stays open for many many years. ”
Doink D.“ Decent tacos, there are better places in town. Including food trucks I hope they revamp their recipe to have a better product ”
Steve L.“ They have amazing food and friendly quick service! They even let me try the filling before I ordered it. Definitely will return. ”
Linda S.“ One word: YUM. I'm sure I've said it in other reviews, but I love Mexican food - tacos, burritos, you name it. Blue Corn is right next to a gaming store that my boyfriend and I wanted to visit on a Saturday afternoon, so we decided to give it a shot and were absolutely not disappointed. The restaurant is the end unit in a small strip mall, so parking is fairly easy to find and there are quite a few large trees that provide some good shade for your vehicle if you stop by on a hot and sunny day like we did. The front counter and dining areas are very clean and tables are nicely spaced to give folks a bit of elbow room and privacy. You can see the grill right behind the register and tons of fresh vegetables and homemade tortilla/etc. ingredients stacked around, and everyone works super fluidly together to crank out hot, fresh, and delicious food to customers. We ordered the fajita chicken burrito and a handful of their signature blue corn tacos with different fillings. Our meals came out pretty fast and they were HOT; it took me a couple of minutes to comfortably handle my burrito because of how piping hot it was in the foil lol. When the gentleman dropped our dishes off, he also asked if we'd like a couple of sides of homemade salsa and gave us the option to choose the spice level. We both chose hot, and he brought back a handful of individually packaged salsas - they were absolutely delicious and had a good kick to them. I didn't end up trying any of the tacos, but given the speed at which my boyfriend ate them... they were obviously very good. My burrito was absolutely delicious!! The flavor combinations of the freshly grilled veggies, chicken, and rice were perfect. Price point was reasonable, especially considering portion size. I only ate about 2/3 of my burrito and was more than satisfied. Location is fairly convenient, especially when we get the urge to visit the game store right next door. Since I took these photos, we've been back a couple of times and I know that there are going to be many more visits in my future. Stop in if you get the chance, and I'm positive you won't regret it. ”
Meghan D.“ In Colorado for my daughter's softball tournament and this was a convenient place to grab a bite in between games. Fast casual ambiance, friendly service and food was solid. I ordered a battered fish taco, which was one of their special style tacos. Those tacos come with rice and beans on the taco. I also got a chicken street taco and an order of queso and guacamole. Those items was slightly over $20. I thought a little pricy. The tacos were solid, not phenomenal but decent . The blue corn chips were outstanding and taste of fresh and homemade, and were thicker than your average chip which I personally like. Queso had peppers in it with a mild spice while the guac was tasty. They were pretty busy and my food came out relatively quickly and everybody was very polite. Overall, a solid restaurant with good food. ”
Abe R.“ Located in an unassuming strip mall, one might not have high expectations, but this place is super clean, spacious, and bright. The owner is very friendly, and when we didn't know what to order, he made helpful suggestions which were on point! We ate there twice in two days while in the area, so that's gotta say something! Our first visit included various tacos including the poblano taco, carne asada taco, chips and queso. The next day included a smothered burrito, shrimp fajita taco and more chips plus guacamole. The blue corn chips were a nice change from the normal tortilla chips, and they had just the right amount of salt. The queso was flavorful and not too gooey or too thick. The guacamole was fresh and delicious. Pay at the counter and food is brought to your table. Just the nicest friendliest family and I love supporting small business. Bus your own tables if you like. This is our go to tie tacos now! ”
Glenda J.“ We came down to Longmont on a chilly Monday preparing to grab some tacos to go and hit up a brewery. Turns out all the breweries are closed until at least 3pm, so we decided to grab a seat instead. It's an order-at-the-counter place with an expansive menu of traditional street tacos, burritos and home specialty tacos. I was feeling the sea this day, so I chose the fajita shrimp and the beer batter fish tacos from the specialty menu. My husband got one of every kind of street taco - Asada, pastor, carnitas, pollo and barbacoa. Both of us selected the blue corn tortilla option because if it's in the name, it's gotta be done! I loved both of my tacos, although I was surprised to find that the bed of Spanish rice was wrapped inside the taco instead of underneath. The pan fried onions and jalapeños were still nice and crisp, but somehow caramelized, and the rice was flavorful as well. The tortillas held together really well and were generously stuffed with the proteins. My husband enjoyed all of his tacos as well, with the barbacoa being his favorite. We also grabbed a horchata since the beer/margaritas aren't available there and enjoyed a leisurely lunch before we sauntered over to an open brewery! ”
Becki H.“ !!!! It's been so long since I've had decent tacos and I found it. No frills but they've got the flavor, quality ingredients, and a tortilla that doesn't fall apart. Food: -Beer batter fish and shrimp: Batter is crispy and not too oily. Pickled veg balances the savory and makes it refreshing despite the mayo sauce. The avocado sauce is yum. -Pastor: Pork is juicy and well flavored. Pineapple adds a nice citrus undertone. Service: Quick and polite. You order and pay at the register. Space: Casual and clean. Lots of seating. ”
