I called a couple of days ago, and had no problem at all.
The lady spoke in French first, but as soon as I said "hello" she switched to English, and we had no problem communicating.
She took all the details, as Rottie has said already, and then repeated them back to me. She also gave me a reservation reference number, but said I could either use that or my surname to let them know when we arrive at Cafe Mickey that we have a reservation.
