welcome to the USA!  i only know the anaheim area,
i guess, since i live in la.  there used to be a
mandarake out here but they moved and then they
closed down for some reason.  i think that there
is still an animate in la, but you'll have to look
them up in an la phone book. there is also manga
house in irvine spectrum.  just follow the
spotlights in the sky. they are at the 5 and 405
freeways junction. then there is super collector's
and noriko's dark harbor, but they are both by
appointment only and you need to call them (they
are in the phone books, though one in central and
one in south.  we have lotsa phone books here).
hope this helps.
