I'm of the belief that good BBQ is something you just won't find in hoity-toity areas. Rich people don't know how to cook, they have personal chefs to do that for them; and poor people can't afford to open restaurants in rich areas. I've never been to Beach Pit for this reason. It looks more like patronizing immitation of the real thing. I have yet to find good Q in areas like Costa Mesa, Huntington Beach, Newport or any of the other more upscale areas in the OC. That said, to find good Q, you must be willing to go into the not so primped areas like Long Beach and Santa Ana. I realize that a person of the frozen tundra probably may not want to venture into the scary areas like Inglewood, Compton and all those other areas referenced in rap songs, so I'll give you a few names of places I've been to that aren't too scary.
Santa Ana is just a quick 15 minute drive inland. There, you will find Burrell's BBQ.

If I'm not in the mood to be standing around in for a long wait and just want something half decent, I wouldn't count Lucille's BBQ out. They're a chain, but as far as chains go, they're ok. I like them more than Famous Dave's. I like their slow smoked tri-tip. Mind you, this IS a touristy place to go. As a member of the Brethren, I encourage you to seek out the real deal elsewhere.

Now... I have to say...my very favourite is in a sketchy area and it isn't for long leisurely meals. It's called Bludso's BBQ in Compton. This is more like the kind of Q I like to make and the sides I like to eat, especially the collard greens, mac and cheese and the red velvet cake. I know, it's in one of those infamous areas... they're on a main road off the freeway so you wouldn't have to weave around in a sketchy area. Just go during the day and you'll be fine. And you'll be supporting a local ma and pa in an area that really needs the business.
