I am not a gourmet, but I love traditional French food.
Here are some of my favorite search pages for finding bistrots and restaurants in Paris. I prefer those with diners' reviews, but also pages with photos of the restaurant can be of great inspiration.
(only in French, but very userfriendly. Very valuable site)
(information can be chosen in English, but reviews are in French. Huge and very valuable site)
(very inspiring list of traditional Paris Bistrots, although highly subjective)
(information can be chosen in English, but then French reviews will not be shown. Very valuable site)
(can be chosen in English. Beautiful site, my favorite. Photos of restaurants and chefs, menus shown with prices. Very valuable site)
(extensive list of Paris winebars, sorted by arrondissements. Very valuable list, although highly alcoholic. Click on "Tous" and then "Rafraîchir" to have both winebars and beer pubs. You can also choose only to have "Bars à vins" or "Bars à bières")
(can be chosen in English, but content is more extensive in the French version)
