Cellarmaker for sure. Seven Stills and Barebottle are also worth checking out. If you have a car, I'd highly recommend Fieldwork (Berkeley or San Mateo location). As for beer bars, like someone already mentioned, Mikkeller Bar, Monk's Kettle, Toronado and Liquid Gold all have great beer...
Was in LA for the weekend and stopped by Mumford brewing.
Cracked opened the Universal Magnetic tonight. NE style IPA brewed with Plato 16.1, Galaxy and Mosaic lupulin powder. Getting mangos, pineapples and citrus throughout. A slight yeast burn but nothing abrasive. Fantastic brew!
