Hi Rene,
Well, it wasn't exactly cheap but I felt it was worth it. My cake was 10 kg, at $60 for 1kg, so you can do the math.
IIRC, The Patissier charges per kg, $45 for choc chip (a firmer version of butter cake with choc chips), $60 for brownie and $90 for fruitcake.
They also do mini wedding cakes packaged individually for your guests. I would really have loved that, but the bill would have been astronomical!
Hope this helps in your decision.
