Waiters at this cafe needs training on how to treat customer otherwise you will loose your loyal clientele. My experience on Saturday made me feel like i'm worth nothing and I ended up drinking alcohol to take away the frustration and anger that I had. Such a high level place to have unprofessional stuff was a shock to me. And I'm not the only one feeling that way.. Please speak to your waiters on how to treat people
