Which of the following scotches is available at Outback Steakhouse?

Johnnie Walker Red is a widely recognized blended Scotch whisky that is often featured on the beverage menu of many restaurants, including Outback Steakhouse. This choice highlights the accessibility and popularity of Johnnie Walker Red among patrons who enjoy Scotch whisky. It's known for its smooth profile and balanced flavor, making it a common selection in casual dining environments.

In contrast, while Glenlivet, Macallan, and Oban are also respected Scotch brands with unique and rich histories, they might not be as universally available at all Outback Steakhouse locations due to variations in regional beverage selections or emphasis on blended options for a broader audience. Thus, Johnnie Walker Red stands out as a prominent choice that aligns with Outback's approach to catering to various customer preferences.
