I decided I'm not a huge fan of the Let's Go series. Perhaps they are intended more for the inexperienced, younger, budget traveler? I preferred and recommend Rick Steves' Paris 2009 as a good alternative.
Not sure why the picture here is messed up. I skimread this again today, and though it's from 2007 and the prices are now obviously out of date, it remains one of the best Paris guidebooks I've seen.
