I love the Arizona-Sonoran style food (especially Botanas) and friendliness at Carlos O'Brien's on Northern so much that I hold my semi-annual VIP Customer event there. While service has always been adequate, I had an exceptional experience on June 20, 2016 when Daisy was my server and seemed to anticipate our every need. I was even more pleased when our eager busboy, Pablo, was super helpful far above simple refills and cleanup. He even picked up my heavy things and carried them to my car for me. I don't know if Carlos O'Briens lucked out and found two service jewels or are now training their serving employees better---my experience on 6/20/2016: the service is as great as the food!
