After months and months of planning I'm now down to just a few more weeks before my return to Paris and am massively looking forward to the trip partly because of for the culinary experiences but had a question regarding etiquette during the meal.

Is it considered rude or gauche to snap a few pictures of the restaurant or plat principal? I'm not likely to be in a 3 Michelin star venue but more the modest bistro or small restaurant and so would expect the reaction to be a little less muted in the more informal venues but would it still draw stares from staff or other patrons? I want to remember the meal with a photo or two, nothing too obtrusive mind you and normally try to quietly ask the staff if it's okay but was curious what others here have seen or experienced on this topic.

I've already worked up a short list of local restaurants around my apartment which is metres off Champ des Mars and was reading reviews and noticed many pictures of the plated food and so was curious to ask the question.
