The Palm Cafe at 209 West 125th Street. The palm was a one of the most well known jazz establishment in Harlem. The photo from 1949 shows the semi-circular awning of the cafe and one can barely make out “Palm Cafe” printed at its circumference. There’s neon signage above the said awning but its hard to make out from the angle of the photo peering west along 125th Street between ACP/7th and FDB/8th Avenue. Jimi Hendrix apparently was amongst the many notables that had their start at this famous club (via source).
