4 Sons, Gothard/Ellis and Bella Terra (Gothard is better
Riip, PCH/Warner and Magnolia/Garfield
Beachwood inside Gothard/Talbert/Slater/Beach and at Warner/Bolsa Chica
Flashpoint, Ellis/Gothard
All worth checking out.
Your can also check out the original HB Beer Company, but it's more tourist attraction than pure brewery.
