Beachwood BBQ is where you want to go.
Avoid Belmont Brewing, and to be honest I wasn't too keen on Rock Bottom's stuff last time I was there, although it's always been hit-or-miss for me. I wouldn't go to Yard House personally. The people who work at Beachwood actually know about beer and care about what they serve. You will not get the same level of service at Yard House. I have been there many times, but they always make me wish I'd gone someplace else.
Beachwood BBQ is also right next door to Congregation Ale House, which, although the service is generally not the best, has probably the second best bottle selection of any bar in the Los Angeles area. I think the service issue is partly because of the weird system they have set up for placing orders and monitoring tables. Also, I have had more than one surly waitress there....although that might be because they are forced to wear catholic school girl uniforms.
