I am a frequent flyer at many restaurants in Phoenix and other cities. Christo's is interesting to say the least. Very rigid service, slow and it seems that if you don't have a reservation they shun you. The manager appears to do nothing and stands around and does nothing to help his staff in the least. If anything, he does a very good job being rude and has a very high sense of entitlement. Their Happy Hour is wonderful because of their bartender AJ as she understands how to treat people and make them feel welcome. The rest of the staff (mainly) the smug manager need to get over themselves. As, your clientele are all blue hairs and will not continue to frequent their restaurant as life takes it course. You need to reinvent yourself if you want to attract a younger patron. There are many new places pushing you out if you don't change your bad attitudes.
