Here's one for my foodie French-speaking soon-to-be-or-already-are-in-France friends: Les 100 meilleurs bistrots à moins de 30 €. Note: The link points to ones in Paris, see the sidebar for those outside the Île-de-France. For the non-French speakers out there, it's a list of "The 100 best 30 € and under bistros."
I've been to two on the Paris list so far this visit: L'Ami Marcel (which was mentioned in the April 2005 Gourmet article "The Bistro Boom"); and L'Epi Dupin. Both were very good and I'd recommend either for a lovely meal. And see, if I were less lazy, I would have written posts about eating there! As penance, if my dinning companions post about the meals, I promise to make the appropriate links.
