What special menu item do guests receive for free on their birthday?

Guests celebrating their birthday at Texas Roadhouse are treated to a complimentary dessert. This gesture adds a personal touch to the dining experience, allowing the restaurant to recognize and celebrate the special occasion for their guests. The dessert typically comes with a special presentation, often enhancing the celebratory feel of the moment. This practice is common in many restaurants, where free dessert or treats are offered to create a memorable experience for the customers on their special day.

In contrast, a complimentary steak, a free side dish, or a discount on the meal are not standard offerings for birthday celebrations. These alternatives do not align with the typical birthday promotion that Texas Roadhouse has established, making the complimentary dessert the correct response.
