Thanks everyone for all your suggestions. I wasn’t able to get in to any of the local (Vaneau) recommendations as they were either closed on the weekend or completely booked.
But . . . funny story. Be careful what sort of energy you put out into the universe as it may just come back to slap you in the face. I ended up on two dinner cruises. Hahahahaha but true.
So, since we couldn’t get into of the restaurants we wanted - and it was Easter weekend - and it was a last minute trip - we heard back from the Calife boat and they had availability for a dinner cruise. So we did it.
And then . . . . i was there all week for work and the clients I was with organized a dinner cruise for everyone on another night. Who would have thought. This one was on Bateau Parisiens.
First - if you were going to do a cruise, of the two I would definitely recommend Calife over Bateau Parisiens. The boat was smaller, much more charming, and the food was much better. Bateau Parisiens’ food was more akin to “hotel” or “conference” food, it was a noisy boat with a wandering flautist and wandering singers with a lot more people in a strange 80’s modern design. I’m not saying the food on the Calife was “destination” cuisine by any stretch but it was perfectly enjoyable.
But - having done the two - I would NOT recommend doing a dinner cruise while in Paris. I WOULD recommend doing a boat cruise down the Seine just not a dinner cruise. On both boats almost all tables are sat so that one person faces out while the other diner faces into the center of the boat. They do not tell you what sites you are passing. And honestly you miss almost everything because you are chatting with your dining companion and/or eating and looking at your plate. I have done the cruise (without dinner) several times with different friends who hadn’t done them before, so I was very familiar with the sites so faced towards the center of the boat on both cruises - and honestly I saw virtually nothing or the wall of the opposite side of the river. On the second cruise I was with several people who had never been to Paris before - and was asked every few minutes what building was which as we cruised down the river.
So I will echo the advice of others to dine on the land and take a river cruise before or after eating - not just because of the food, in fact more because of the overall experience. And from past personal experience if you do that I recommend taking the boats from Pont Neuf, near Notre Dame, instead of the boats from near the Eiffel tower. Same tour but those boats only narrate in French and English, the boats from the Eiffel tower do (if I remember correctly) 4-5 languages. So on those boats there is constant talking in languages that you just don’t understand anyway.
Note - It was very cool (even cold really) while I was there (late April) so both cruises had their roofs closed which likely impacted what we could see as well. The Calife may be much different (in a positive way) if weather permitted them to have the top fully open (the front 1/2 of the boat had a class ceiling while the other 1/2 had a canvas cover - you can not request location when booking). I’m not sure how much they can open up the Bateau Parisiens even in the summer.
