Which menu item is known for its Southwestern flair at Texas Roadhouse?

The Smokehouse Burger is recognized for its Southwestern flair at Texas Roadhouse because it typically incorporates ingredients and flavors that are characteristic of Southwestern cuisine. This may include spices, jalapeños, onion rings, or a specific sauce that adds a kick to the burger, enhancing the overall flavor profile.

The BBQ Chicken, while flavorful, is more aligned with traditional barbecue rather than a Southwestern style. Chili-Cheese Fries, although delicious, generally center on comfort food rather than incorporating distinct Southwestern elements. The Spicy Chicken Sandwich may offer some heat but does not have the same Southwestern influence as the Smokehouse Burger, making it the standout choice for that particular flavor profile.
