Dined at California Grill this eveining 3/19/16. Food was good,, service was good. My wife was drinking iced tea, glass had globs of something caked onto outside of glass. It was not noticed because the glass was turned away from her line of sight. The waiter apologized and should of noticed it. Waited for a booth, then several couples came in after us and were seated before we questioned, why we were not seated first, then they managed to seat us. Weve eaten in the place several times, but dirty glass was unacceptable. It is expected you will have utensils not clean on occasion, but this glass was disgusting. Asked cashier to speak with manager, took a while for manager to come forward. I felt the manager was not interested in my complaint. I left my nimber with the cashier, will see if I hear from the manager
