There is a law in France that states that you can bring your own bottle of wine to a restaurant. The restaurant cannot prevent you from doing this. Thus, you can either bring your favorite wine, or a cheap bottle of wine without having to worry about getting ripped off by the house. Despite this law, will bringing your own wine to a restaurant cause problems? I'm imagining the chef or waiter spitting in my food because I'm not buying their wine, or perhaps giving me bad service in some other form. After all, they're not making a profit on it and my tip must be less because my bill is lower.
This Wall Street Journal piece has some good guidelines, but I won't be able to, as the article states it, "Get to know the place first" because I'll be moving from one place to the next. Also, I really may not want to visit the same place twice because there is so much to do.
