So I just recently got a growler and so far so great. The only problem I am having is finding places where I can fill up. Does anyone have any recommendations as to location in the San Francisco Bay area (South Bay would be great). There seems to be surprisingly little, easy to find information on the internet about this.
It's not quite the South Bay but close. I've seen them fill growlers that do not have their name on them.

If you like IPAs or APAs, the Bombay Bomber and the Double Play are worth a try.
Most places (generally everywhere and certainly in Bay Area) allow only their own growlers to be filled with their beer. Thus if you buy a Growler from ISO Beers, they will not fill it at Original Gravity 2 blocks away (both very decent places).
It is just not good business - they want you to come in and pay premium on their single draft beers. So if you want to take some to go they want to at least win your loyalty by giving you discount on Growler fill, but make sure you come back to their brewery.
