My wife and I along with another couple took this dinner cruise as part of our package. It was an included tour, we just had to pick the night. It included a welcome cocktail, a full bottle of wine per couple (choice of red, white, rose), large bottle of mineral water and the 3 course meal.
The trip we had would cost 85 euros and leaves the marina at 915 sharp. The boat was about half full when we sailed. The service was very good and we were pleased with the whole experience. The ambiance is very nice, great views, music and table settings.
The food is VERY good and well worth the cost of the whole experience. The menu is set for appetizers and deserts, everyone gets the same which is 4 different appetizers and deserts each. Not large portions of course but very good. For the mains you choose from 3, Cornish hen, Salmon or beef. Beef requires a 7. euro surcharge so we didn't get it. We had both Salmon and Cornish Hen at our table. Everyone loved the meal and ranked it high for quality, presentation, etc.
The tour on the river is wonderful, doesn't feel like your on a boat as others we've done in Hawaii, etc. The lights along the river and sights were excellent. At the end part you are by the Eiffel Tower to see the great light show at the top of the hour, 1100 PM. It was fantastic!!!
The boat is back at 1115 PM and you are quickly able to disembark. We took the metro to get down to area on north side of Seine. Used the Tulleries Station on the #1 line which gets you out on the Rue de Rivoli. A very quick walk past the west side of the Louvre takes you over the river and to the Marina where you embark. We took a cab after it was over, taxis are waiting on the street right at the site and it was easy to return to hotel.
All in all, this was an excellent experience, all four of us would recommend it and would do it again. To top it off the vessel is air conditioned so that was really nice when the temp's were in the 30's.
