I'll soon be visiting your area during the week. (no Friday or Saturday nights)

Any advice on places of interest near 26th or 28th Street?

Like strip clubs (not just topless), adult stores, sex clubs ...

I'll be visiting alone, so if there are "couples-only" places, I'll have to skip them this time.

Why don't you contact Miki the MILF????  She is conveniently located to your "places of interest", and is a one-of-a-kind.  terrific lady, and an unbelievable experience.
