Good Road Bike Shop in LA/OC?

Hi,

I'm looking to buy a road bike and I'm having a hard time choosing a good local bike shop. I bought my last bike at Jones Bicycles in Long Beach, but they seem to be dedicated to fixed gear bikes now. I'll travel pretty much anywhere in LA/OC to get a good fit and people who know what they're doing. Anybody been to ARoadBike4U in Irvine, or Fullerton Bicycle? Any places I should avoid?
Please help.

I didn't find the right solution from the Internet.
