How funny, I will be there from Jan 18-22 and have been making a styleforum-esque supermap on my google maps for the last few days. I am staying in North Marais and from what I have found so far, here are some interesting looking shops and restaurants:
Mini Colette (from what I have read) - Merci
I am not from France nor have I ever been, so these recommendations are based solely on my personal research. Also, I acknowledge that some of these may have already been mentioned. These are just a few from my list, looking forward to any other recs posted here.
As for what to read about, I have been interested in Melindagloss much recently and I am looking forward to visiting their shop.
It looks like I am missing the cool stuff @LA Guy you mentioned you will be covering, know of anything happening earlier in the week?
