The Great Gatsby, side-street drugstores

I'd like to know if the word "side-street" in the following excerpt from the chapter Seven of The Great Gatsby is an equivalent of "side-street" in the sense of "underhand", "secret", "sleazy":

“I found out what your ‘drug stores’ were.” He turned to us and spoke rapidly. “He and this Wolfsheim bought up a lot of side-street drug stores here and in Chicago and sold grain alcohol over the counter. That’s one of his little stunts. I picked him for a bootlegger the first time I saw him and I wasn’t far wrong.”

Thank you.
