You will enjoy the Stadium Club, albeit somewhat crowded and noisy by Game time. Wide variety of food, and full bar, upstairs and down. Food replenished at halftime, more sushi dessert and ice cream. Your wife has no worries about her Trojan gear. Visitors are generally treated with respect. Members understand tickets change hands (for a reason).
I agree with Mama Bear. Cal fans at CMS are generally friendly and tolerant of opposing fans.
UNLESS 1. those fans are boorish or drunk or both. Or 2. Those fans are part of Stanfurd's so-called "band"
The only times I witnessed trouble has been (usually against UO) when the drunk Duck fans (sitting in the middle of the Alumni section) started yelling obscenities at the Cal fans around them.
Eventually they were removed by the authorities.
Another time a year or so ago two drunk Duck fans were jumping up and down with each Duck Score and carrying on well beyond normal fan behavior. Eventually one of the drunk Duck fans slipped and hurt himself badly. An EMT had to be called to help him out of the stadium. Even then the Cal fans helped this obnoxious boor up and assisted the EMT.
BTW I am intentionally ignoring the many episodes where the student rooting section bombed the Stanfurd "band" with water balloons. I write those episodes off due to justified retaliation.
