A minimum of 1 security guard is required for events serving alcohol.
Additional security may be required based on:

Catering at the Diamond Bar Center is designed to support a wide range of events. 🍽️

All caterers must provide a county-issued public health permit to serve at the venue.

For events in the Grand View Ballroom, caterers have access to a fully equipped catering kitchen, which includes:
• Two restaurant-grade warmers
• Conventional oven
• Refrigerator and freezer space

The Diamond Bar Center is a non-cooking facility, so all food must be prepared off-site. Catering staff should plan to use chafing dishes, warmers or available kitchen appliances for service.

To learn more about catering requirements, call the Diamond Bar Center at 909-839-7065.
