Because cakes are meant to be eaten - all part of it. It's not meant to be disposed (*ehem*fondant*ehem*) or fake (*ehem*dummy*ehem*) just for the sake of looking pretty. And it's not meant to be grandieur (*ehem*eight-tiers??*ehem*) only to be binned later on.
I want to be able to share my cakes with my guests, and I want them to enjoy it as much as I do (being the cake-loving person that I am). So when it comes to deciding my wedding cake designs, flavours and concept, it was one of the easiest choice I've ever made.

3 cakes. 3 flavours. 3 separate tiers. And fresh flowers. And maybe... after the cake-cutting ceremony, I'd have the cakes transferred to the dessert table so that it'll be easily accessible to my guests. Well.. that is, after I've had my fair-share of the cakes itself. (^__^)
(Q: So how many times have you eaten cake at a wedding? Seriously.)
