Cake at GTG?

Does anyone know where the cakes came from that were served at the GTG? I just loved the cake that had the raspberry mousse inside(not the chocolate cake) but unfortunately do not know what kind of frosting it was - maybe the buttercream??? I know it wasn't the cake with the foundate (is that how you spell it?). I need to pick my wedding cake soon and I am somewhat picky with cakes. I just loved that cake I had (i ate 3 slices ) and would love to serve it at my wedding. It wasn't too sweet but so good! Now I'm drooling all over my keyboard!
