West of the 405.

I used to live right near the Promenade and could walk to everything. Now I live closer to the 405 in Brentwood and I can still walk to a lot of places, but I can definitely bike everywhere I need to go. SaMo is great about creating bike lanes too.

You aren't going to find tons of walkability otherwise, unless you luck out and do something like work *and* live right by a hub with lots of restaurants/grocery stores/shops/etc. I'm sure there are other areas that could be described as walkable, but none as walkable as the Westside imo.
