What is Pip's first impression of London?

Pip's first impressions of London are visual. After having
never really been in the city itself, he had no idea how dirty and ragged it could be.
This is just part of the era, but it is particularly an aspect of London that Dickens
wanted readers to notice.

Pip finds the street gloomy, and
the description of Jaggers' office is terrible. Many dark overtones are used, and the
disjointed joining of buildings made Pip wonder why the city was designed that way. The
coach Pip had ridden in to get there was described as
weather-stained and the rags therein were described as
moth-eaten.  Jaggers' office is described as having greasy walls as
people intimidated by him backed up. Being so close to the courthouse, the area around
Jaggers office was described as pretty dirty as are most inner-city places
today.

This description is important because it foreshadows
Pip's experience there.
