Don't bother with this so called tour. All it involved was a bus ride to the tower and then to be dropped off at the restaurant. The boat trip is an open ticket which you can use any time and do basically do yourself. The menu was fixed with NO choice. It was nice however.
The only reason we booked this tour was because it included a booking at the Eifel Tower 58 Restaurant and we couldn't book direct at short notice. If you can arrange your own booking strongly suggest you do as this was somewhat of a Rip Off.
