The Jazz Cafe has quite a high ranking in the musician world. It features some of the best musicians on the planet, however I have long since stopped going because of their poor customer service.
Far too many times I have been offended by the unprofessional behaviour of the staff there. Just as one example, there have been times when I've not been able to make a concert, and was told quite bluntly that I wasn't entitled to a refund or a change of concert. The couple of times this happened, it was either staff in the ticket office or just inside the venue itself. The staff in question seemed to be offended, as though I was taking money out of their pockets, personally (!)
Another time I wasn't happy with an order from the kitchen, and to cut a long story short, I was suspected of something (I don't know what), and my complaint was refused! I have not returned since.
It is difficult for me to complain about fellow musicians, however, as a teacher of music I feel The Jazz Cafe staff are responsible for a major music venue and need major re-training. It is run by louts pretending to be a classy establishment. It is not somewhere I'd recommend for the general concert-going public. If you're desperate to see your favourite artist, then go. Just make sure you don't run fowl of their many eccentricities.
