What type of lager is mentioned in the Happy Hour drinks list?

Longboard lager is the correct choice because it is specifically noted on the Happy Hour drinks list, distinguishing it as a featured option for patrons during this time. This lager is often recognized for its smooth, refreshing taste, making it a popular choice among customers looking for a lighter beverage option.

The other choices, while they are well-known beers, do not typically appear on a Happy Hour drinks list at Cactus Club. For instance, Blue Moon is a Belgian-style wheat ale, distinct from the lager category, and Budweiser and Heineken, though popular lagers globally, are not highlighted in the same way as Longboard in this context. Therefore, Longboard lager stands out as the specific lager mentioned.
