About Castle Catering In 2009, we entered our 25th year of providing fine social catering to the San Gabriel Valley Area. It has been a wonderful two decades doing all types of catering for a wide variety of occasions. Corporate catering has included business openings, retirements, company picnics and holiday parties. We have also catered well over 1, 000 weddings and not lost any enthusiasm or understand that we are a large part of the responsibility for what is considered the most important social event of a lifetime. Castle Catering has a philosophy about event planning. Make the planning process fun. You are planning an event for your guests to have a wonderful time... so enjoy.
