A more thorough explanation:

A drinking shop, also known as a dram shop, is a place where alcoholic beverages are sold, such as a bar or saloon. It is an archaic term that is not commonly used today.

For example, in the 19th century, people would often go to the local dram shop to socialize and drink alcohol. These establishments were often seen as a place for men to gather and relax after a long day of work.

Today, the term dram shop is more commonly used in legal contexts, referring to establishments that can be held liable for serving alcohol to someone who then causes harm to themselves or others.

Overall, a drinking shop or dram shop is simply a place where people can purchase and consume alcoholic beverages.
