2.8 miles in Excelsior

I'm trying to figure out how to describe the Excelsior neighborhood. 

It's similar to the Mission, but mellower. 

 

Like the Mission, Excelsior has ample murals and neighborhood pride.

It also has several schools, including the City Arts & Technology School.

Naples Street. Oops. 

There's low, and then there's LOW.

Judging by the amazing animals peeking out from the curtains of this mysterious establishment, I am indeed sorry that they are closed.  Does anyone know what this place is on Paris and Brazil Streets?
