When not in use as a meeting place for Castro Valley's Masonic Lodge #551, this large space can be rented for parties, gatherings and functions of all kinds. The center's banquet room can accomodate 150 for dining and 260 for dancing. The even bigger "Lodge Room" can seat 125 people on leather benches around the room; with folding chairs in the middle, the room can hold 315 people. There's ample parking and a fully equipped commercial kitchen, and event dates are booked on a first-come, first-served basis.
