What Fiesta Restaurant Group does

Fiesta Restaurant Group was a publicly traded restaurant company (NASDAQ: FRGI) that owned and operated Pollo Tropical (Caribbean-inspired grilled chicken) and previously Moe's Southwest Grill. In 2022, Fiesta Restaurant Group was acquired by Authentic Restaurant Brands (ARB), a private equity-backed restaurant consolidation platform headquartered in Addison, Texas, and Fiesta ceased to exist as an independent public entity. Following the transaction, Pollo Tropical became one of five wholly-owned regional restaurant brands within ARB alongside Primanti Bros. (Pittsburgh-based sandwiches and pizza), P.J. Whelihan's (wings and sports bar), Mambo Seafood (Gulf Coast seafood), and Tavern in the Square (sports bar and tavern).

The combined platform generates over $1B in annual sales across 230+ restaurant locations, with a collective 200+ years of operating history. ARB operates as a multi-brand restaurant operator and acquirer, working closely with brand-level operators to deploy business intelligence tools, operational expertise, menu design support, and marketing strategy while preserving each acquired brand's identity. Named operating partners include PJW Restaurant Group (P.J. Whelihan's), Mambo Seafood, and Tavern in the Square, whose CEOs are quoted on the ARB website.

Revenue mechanics are driven entirely by same-store sales and unit-level economics across the five restaurant brands; no franchise royalties, technology licensing, or non-restaurant revenue streams are disclosed. Distribution is exclusively through owned restaurant locations across regional U.S. markets. The company employs 10,000+ people and is led by President and CEO Dirk A. Montgomery. Recent 2025 third-party press coverage in Forbes and FSR Magazine highlights revenue improvement at Pollo Tropical under ARB ownership and frames the platform as a billion-dollar growth engine for regional restaurant brands.
