Which area in London during the Restoration was known for low quality literature produced by hack writers?

Grub Street is historically recognized as a term that emerged in the late 17th century to refer to a specific area in London infamous for its association with low-quality literature and hack writers. These writers were often driven by the need to produce quickly and cheaply for mass consumption, leading to works that lacked literary merit or originality. The term "Grub Street" eventually evolved into a metaphor for any place where writing of a poor quality was produced or where writers worked under unfavorable conditions.

While other areas like Soho, Covent Garden, and The Strand have their own cultural significances and contributions to literature, they are not synonymous with the negative connotations and reputation that Grub Street garnered during the Restoration period. Therefore, Grub Street distinctly stands out as the correct answer in this context.
