I will spend a month in Paris in November/December in a work/professional capacity. Although I have been to Paris several times (mostly as a tourist), this is my first opportunity for an extended stay. Despite the mostly professional nature of the stay, I will have sufficient time to explore and experience the non-tourist aspects of this wonderful city. Let's start with a couple of questions:

1. Although I intend to walk to my work location on most days (5th arrondissment), I intend to use the Metro often. I know about carnets/tourist specials but wondered if something similar exists for a month long stay. What do the locals use? Pay fares as needed or does a monthly pass exist?

2. I enjoy small jazz venues and, as a (serious) amateur photographer, have a nice collection of performers (natural light, no annoying flash) that I would like to expand. Recommendations appreciated.

3. Major fan of food* and wine. Recommendations of local small restaurants in the Jardin du Luxembourg area would be appreciated. I enjoy going back to favorite spots often and getting to know the owners, staff, etc.

Thanks for your advice and suggestions.

*Just noticed on another thread that November is game season. I really enjoy wild game, especially with a nice red wine (the former because of my rural upbringing).
