There are pockets of asian communities, but spanish is ubiquitous.
But you may be right about me not being there. Latin-americans may be more willing to speak spanish around non-spanish speakers. The numbers just work out that way.
My personal theory on this is that spanish speakers have been in California longer than English speakers (thereby having feelings of relative native status), while various Asian language speakers feel the obligation to include non-speakers in their discussions when said non-speakers are around because asians and anglos have been in the bay for roughly the same amount of time (since the gold rush).
Although ... Asian language speakers never feel the need for linguistic inclusion when hispanics are around. Not sure about the dynamics on that one. Might just be good ol' fashioned racism.
