If one takes the time to sit back & look at the clientele, the staff & musicians/ performers one will notice the preponderance of Caucasian-ism. (ie. its 'white commercial Jazz)
NOTHING wrong w/ European (white) Jazz - I enjoy it thoroughly.
However, if one is looking for the real deal, one would do well to check out the Jazz Showcase in old Dearborn Station. (where the staff, clientele & performers are largely African/ African American)
Both venues are 1st class & will leave one totally satisfied...
