I want to know the answer to the following question:
In what British city did gin houses first appear?
All the background I'm provided with is that "These bawdy, loud and unruly drinking dens so often described by Charles Dickens in his Sketches by Boz (published 1835–1836) increasingly came to be held as unbridled cesspits of immorality or crime and the source of much ill-health and alcoholism among the working classes.". Is that enough to answer the question?
Answer: no
