For a restaurant, I would recommend Le Coup Chou for ambience and genuine Parisienne dishes at a reasonable price. Myself and Mrs. Carpedeum have returned there every time during recent visits (recommended to me by a French work colleague).
I don't know if this place has changed hands since Carpedeum's recommendation in 2010, but I ate there last week and wouldn't be in a rush to return. We waited easily 10 minutes, if not longer, just to get a menu. When we did eventually order, our food arrived within minutes, suspiciously quickly!! Just as well I wasn't starving as the portions were small. I had the boeuf bourginon served in small soup bowl: 4 pieces of meat and 2 small potatoes (€20). In contrast, the chocolate mousse could have fed 2 people. My dining companion had veal and rice, no vegetables with either dish. With a nice bottle of Cotes du Rhone (€21), the bill came to around €90 for two. The most annoying part of the experience was the young waitress who was trying to show off her bit of English at every opportunity when it was evident we both spoke competent French. Not just rude but downright irritating. The decor is lovely but I wouldn't seek it out again.
