We had breakfast for two for points ...
We were there in 2004 and got breakfast for two for either 2k or 3k, I cannot remember, but I think it was 2k. In any case, the price of breakfast was 50 Euros per person, so given the exchange rate of the day, it was a $125 breakfast. Basically, the food was good, but nothing worth that amount of money - the price is for the canalside table.
All in all, we enjoyed our stay there. It is a nice place and its location could not be much better.
