After having such a great experience opening our first original concept in Longmont, The Roost, a craft casual American restaurant, bar and venue, we were so excited to find another great downtown location for our second restaurant. We created Jefes Tacos & Tequila at 246 Main Street, Longmont, Colorado in April of 2016.

Chef/Owner Sean Gafner was raised on a farm in California where his comfort food came from great taco trucks and small Mexican restaurants. Jefes was born out of this deep love for authentic Mexican food as well as a passion for fresh, local, sustainable ingredients prepared in a unique way. Our Menu boasts of great seafood like wild Hawaiian yellowfin tuna, Dungeness crab, wild Pacific snapper & bay shrimp as well as beef and pork raised on a local, organic ranch right here in Longmont by Clint & Mary Kay Buckner.

Jefes’ bar program also combines the authentic with the modern by seeking out over 100 amazing tequila and mezcals and serving them with care and expertise. Customers can sample neat pours by ordering a flight or try them in one of our original signature cocktails. Jefes has 16 draft beer lines pouring incredible local beers as well as imported Mexican favorites.

Another ingredient unique to Jefes is that we’re always bangin’ a great mix of old school hip hop, so you may acquire a new skill of eating tacos while bobbing your head!

Since their very first visit, the Gafner’s quickly fell in love with the city of Longmont and couldn’t be more excited to put some roots down in the beautiful state of Colorado!

Giving Back

The same as with our other restaurants, The Roost and Smokin Bowls, Jefes is committed to giving a minimum of 10% of all profits directly to local non profits. All three restaurants also give 10% of all profits back to our staff through cash bonuses.
