[Paris] Early May affordable recommendations

I’m thinking of Polissons if you’re around Montmarte, I don’t know if that fits in your budget. If not, there is always Bouillon Pigalle. Coq & Fils on Montmarte has a 18€ dish of the day, which is usually a chicken dish: poule au pot, bouchée à la reine… Eels, half way between Montmarte and Beaubourg has a 29€ lunch menu with 2 courses.
