Another different museum is Baccarat (historic and current artistic crystal) on the Right Bank. It has an interesting cafe.
A longstanding top fish restaurant is le Divellec (spelling?) in the 7th, near the bridge that goes to Place de la Concorde. It's expensive and requires reservations. For seafood, there are the old classics near Blvd Montparnasse such as la Coupole and le Dom. They're not cheap either and can be busy.
Le Divellic is reported on many websites as closed. The Rodin museum is undergoing a big renovation and has limited offerings. As for Le Dome and La Coupole, many consider these as catering to tourists, and neither is in the top 1,500 restaurants in Paris on Trip Advisor. Finally, the Baccarat Museum, while an interesting place to drop in if you're in the area, is not in my view an attraction to build a day around.
