That the Granada Hills store was only 2 miles from the
famous Knott's Landing culdesac?  Many people thought it was along the
peaceful coast but it was really backed up against the noisy and
busy Balboa Blvd.  The street was named Seaview Circle in the
series but was actually Crystalaire Place. 
I found the street because the producers left
the addresses on the house and they
were viewable during the shows. 
I got my Thomas Bros. map out
and looked for that address on a culdesac
and came up with some possibilities. 
I tried Crystalaire Place first since it was down the street from work and when I drove into the culdesac my mouth dropped!  There were the houses from Knott's Landing!
Over the years I would go there during lunch and see lots of tapings and it was really cool to see all the famous actors.  Alec Baldwin was one of the nicest actors there even though his character Joshua Rush was convincingly mean.  This shows how good of an actor Alec was!
