What does "speed rail" refer to in a bar setup?

"Speed rail" refers to a well-organized shelf for often-used liquors situated within easy reach of the bartender. This setup is crucial for maintaining efficiency and speed during service, allowing bartenders to quickly access the most frequently requested spirits without having to search through a more extensive collection.

In a bar setting, the speed rail typically holds commonly used bottles like vodka, rum, gin, and tequila, arranged in a way that promotes quick pouring. This design helps bartenders minimize preparation time during busy periods, ensuring that they can serve customers promptly and effectively. The correct answer highlights the importance of accessibility and organization in high-paced environments like bars.

The other options represent different elements in a bar but do not specifically embody the primary purpose of a speed rail. Bar stool setups, cocktail shakers, and areas for cleaning glasses each serve vital functions in a bar, yet they do not pertain to the layout or organization of liquor meant for efficiency in serving drinks.
