Wally's Café, Boston
Amazing live jazz every night of the week. An incredibly small venue so I'd recommend getting there earlier if you want a seat. Very intimate and outstanding jazz musicians. Each night is a different musical theme (i.e. Latin, BeBop, Blues, etc.)
Dress Code: anything goes
This is THE most multicultural night life spot in all of Boston. All nationalities and ages seem to be represented! There is great live jazz and R&B every night of the week. Many of the musicians are from the nearby Berklee College of Music. The place is small and gets packed! So, on a Fri or Sat night, I would recommend you come early!
Dress Code: There is no dress code.
