I ordered thomas birthday day from Maixim last year. But, they just add a piece of 'Thomas' chocolate on the top of the cake.
It's still look nice, and my son loved it.
This year, I wanted to be better and my son wanted Gordon. I went to 太子貴族 and order a very nice Gordon cake. If you want to see, can pm me and I sent the photos to you; They have many styles of Thomas cake.
