With the exception of one location, Taqueria del Sol will now keep the restaurant strictly in-house. The Nashville unit, located at 12th Avenue South in the Music City, is the lone franchised restaurant still standing. This time, the expansion model will be very straightforward: All future Taqueria del Sol locations outside Nashville will be run by the same people who invented the original. Taqueria del Sol was born out of requests from guests at the full-service diner, who wanted the restaurant to start offering lunch service.

Key Takeaways:

• Back in 2010, Taqueria del Sol unveiled its plans for the future. The Atlanta-based fast casual, through a wholly owned subsidiary, was entering the franchise game—a rather intriguing prospect considering the brand’s resume.
• Three years earlier, the 10-year-old Mexican- and Southern-inspired concept, which began as a converted café in 2000, was named a “Top American Restaurant” by Bon Appétit.
• There are four company-owned stores, all in Georgia, and those restaurants remain rooted in local dining lure. Written up in national publications like USA Today, the counter-service eatery often sees a 20–30-minute wait and lines that snake out the door.
