What is a unique feature of the garnish for a Buster's Bloody Mary?

The unique feature of the garnish for a Buster's Bloody Mary being a skewer with bacon is significant for several reasons. This choice highlights an exciting and savory twist on the traditional Bloody Mary garnish, which usually features simple additions like celery or olives. The inclusion of bacon on a skewer not only adds a bold flavor that complements the drink but also introduces a creative presentation element that enhances the overall experience.

The bacon skewer represents a trend in mixology where savory, hearty garnishes elevate the cocktail beyond a mere drink into a more substantial offering. This feature sets it apart from standard garnishes, turning the Bloody Mary into a more indulgent experience, aligning with Dave and Buster's fun and engaging dining atmosphere.

In contrast, the other choices represent more conventional or less distinctive elements. While lime wedges, celery salt, and all-vegetable garnishes might be common in various Bloody Mary recipes, they do not reflect the unique and playful spirit that the bacon skewer embodies. Thus, the choice of bacon as a garnish distinctly enhances the character of the Buster's Bloody Mary.
