Weekend in Paris! Seeking dinner recs near Eiffel Tower and thoughts on night river cruise?

My husband and I are heading to Paris for a romantic weekend getaway! We arrive around 7 pm and our BnB is a 15-minute walk from the Eiffel Tower. We're planning a night river cruise around 11 pm, but before that, we'd love some dinner recommendations in the Eiffel Tower area that won't break the bank. We're looking for something with a nice atmosphere and decent food, not just a quick bite. Any suggestions?

Also, has anyone taken the night river cruise? Is it worth the hype? We're excited to see the city lights, but want to make sure it's not just a tourist trap.

Any advice or insider tips would be super appreciated! Thanks in advance! 😊
