Starbird Chicken opens at the Castle Rock Promenade. The Mexican-restaurant block just got a chicken concept three doors down.

Starbird Chicken opened its second Colorado location on Monday, April 27, 2026, at 6360 Promenade Parkway in Castle Rock. The California-born premium fast-casual chicken chain is operated locally by Whiplash Holdings, a Denver-based hospitality group that signed a multi-unit deal for seven Greater Denver locations. The first Colorado Starbird opened on Federal Boulevard in Denver in September 2024.

The Castle Rock build is the first Starbird outside the Denver metro core and the company's first true suburban play in the state. The menu reads more upscale than the typical fried-chicken concept: free-range chicken, hand-cut tenders, sandwiches built around Nashville hot, classic, and signature roasted-garlic flavors, plus a vegetarian Vegan ChicKn line that's been on the corporate menu since 2018. Pricing runs roughly $10-14 per entree, which puts it above Chick-fil-A and Raising Cane's by a couple of dollars and below a sit-down restaurant.

Why the location matters. The 6360 Promenade Parkway address is the third restaurant on a single block of Promenade. Savina's Mexican Kitchen sits at 6361 (literally across the parking lot). Los Dos Potrillos Castle Rock at 6370 is two doors down. With Starbird now open and Lazy Dog Restaurant & Bar in development a half-mile away on Alpine Vista Circle, this stretch of Promenade Parkway has quietly become the busiest restaurant cluster on the south side of Castle Rock, rivaling Wilcox Street in volume of new openings over the last 18 months.

The format play. Starbird is positioned as a competitor to Chick-fil-A in the premium fast-casual chicken category, which has gone from a one-brand market to a six-brand market in five years. The Castle Rock location will run a counter-order model with mobile pickup, dine-in seating for around 50, and a small drive-through window that the lease and the building plan suggest will be a meaningful share of the volume.

What we'll be watching. The lunch traffic is the test. Castle Rock has limited drive-through-quality fast-casual options south of Founders, and Starbird is betting that the Promenade audience will pay $12 for a chicken sandwich the way they currently pay $10 at Chick-fil-A in Lone Tree. If the lunch volume holds through summer, expect Whiplash to accelerate its remaining six locations. If it doesn't, this becomes a pricing-mismatch story.

We'll do a venue editorial after we've eaten there three times across two months.
