Not far from métro Cambronne in the 15th in Paris you find this popular Parisian restaurant on a side street.
They have a very affordable 29 euro menu (three courses, or two for 26€) that will give you a very traditional French meal. If you have that kind of preferences you can get andouillette (grilled sausage from intestines), rognons de veau (veal kidney), or veal liver. They also serve various grilled fish (e.g. a delicious filet de bar grillé) and meat (e.g. an excellent and juicy grilled bavette). To start with you can try the terrines, or the original ravioles de Royan (quite different from Italian ravioli) in a cream and garlic sauce, or a salad with crayfish (with a small supplement, as several other dishes have too).
To finish you can have my favourite, oeuf à la neige façon Marie Edith, poached whipped egg-white in vanilla and caramel sauce, divine.
The wine list is short and traditional. A modestly priced wine is e.g. JL Colombo’s Côtes du Rhône (red or white – 26€). All is very old-fashioned French, almost as if you were in the country side. It is often fully-booked, so call ahead.
