Do yourselves a favor and find Eagle Rock Brewery's "Populist IPA" on tap with nitrogen. I would describe it as "Boddington's on steroids," a very creamy yellow-gold English style ale. It is some of the best beer I've had in a long while.
I had it a few weeks ago at 326 Beer & Wine at Farmer's Market, but they are now out of it. Eagle Rock's website shows that they serve their beer in a lot of places in LA, but one of its representatives say they "rotate taps a lot" so it's a hit or miss.
But if you've got a good local beer bar you frequent, demand this stuff!
