In regards Knowlwood's in Fullerton, I have been asked to post the following link:

This group in which I am usually one of the participants, meets for dinner and good rail conversation of all kinds (even sometimes transit talk).
We meet the 4th Monday at Knowlwood's (there are some rare exceptions but they are noted in advance).
If you stay late enough, members of the group venture over to the Amtrak-Metrolink station to view the eastbound Southwest Chief which arrives about 7:15 p.m.
FYI.
