Depends what you're in the market for, but if you're going for a better road bike (possibly more high end) and to review with experienced folk, check out Velo (in Atwater Village, Los Feliz area), http://www.yelp.com/biz/velo-studio-los-angeles-2.
if Bike Kitchen is the place next to Scoops, just off Melrose west of Vermont-- that's the one I recommend! super nice dudes. and closer to you if you're in Hwood
