Golden Road is a bit of a haul from Anaheim.
For closer ones than that, try Tustin Brewing, Noble Ale Works, TAPS Fish House & Brewery (not really set up like a typical brewery--more of a restaurant that makes excellent beer), Cismontane Brewing, Strand Brewing, Monkish Brewing, El Segundo Brewing, and if you call them in advance, I think you can get into the newly reopened Angel City Brewing in downtown LA.
Also be aware that Beachwood has two locations, and the one closer to Anaheim (Seal Beach) is not a brewery. The place in Long Beach is a brewery, however.
I don't normally visit tasting rooms during the day, but Beachwood BBQ is open all day, as is TAPS.
For a recommendation on a fantastic (non brewery) craft beer location close to Anaheim that is open during the day, try Hollingshead's Deli in Orange, CA. Extremely friendly guys running the bar, excellent sandwiches, and one of the better bottle selections you are likely to see in the area.
