I guess cruise dinner on the Seine is more about an experience than really the meal. I would prefer going just for the cruise with a glass than the whole dinner. A quick search shows no French food magazine has any recommendations on boat diner. Maybe you can consider dining at the Eiffel Tour, Le Jules Verne offers comparative better food than a cruise meal. But I tend to agree with @PhilD, don’t waste a meal if you are a food lover.
A 5 minutes walk from the metro, you can find Quinsou, which I like a lot. Montée (slighter further away from your place) is also strongly recommended by several diners in HO. Full report here:
Slightly further away in the 7th, Tomy and co is a new place you shouldn’t ignore. Tomy Gousset has been cooking in Pirouette, he left and opened his own restaurant.
