Hi, I'm relatively new to this forum. I'm in the Hollywood Hills. I've found a few great places to shop around the area. One is Synergy Diet in Pasadena, which also has a website, synergydiet.com. They have a large variety of fresh baked breads, rolls, brownies, and soft pretzels, as well as tons of packaged low-carb products. If you plan to do a big stock-up, it could be worth the drive from Orange County or the South Bay. There is also a chain of sports/fitness supplement stores around the area called Nutri-Peak that has great prices on supplements, protein powders, low-carb bars and some food products.

Hope this helps!
