I just scanned this thread, so if I repeat anyone, I am sorry... however, I just did a California run last month where I toured 7 breweries and spent time at countless bars...
My suggestions (brewery & bars) would be:
Dont miss the tour at Lagunitas
in Petaluma if you can (3pm daily). That was awesome!
has a Pub in Santa Rosa with great beer and great food (their pizzas are awesome!)
in San Francisco with their "Live Free or Die IPA" is awesome! They also have great burgers and it's 2 blocks from AT&T Park
in SF - if you can get on the list for a tour, do it... but book it today if you havent already, cause they fill up FAST!
In the LA area:
in Fullerton - they have an amazing IIPA called "Knucklesandwich".
- a chain of bars that have anywhere from 130-220 different taps. Amazing selection and just seeing that # of taps, holy cow!
in LA is a great place to hang out. Its a great bar, with a world-class chef and a really good selection of beers on tap... including Pliny The Elder
Theres a few for ya that I hit last month and really enjoyed!
