Ganache Patisserie (http://www.ganacheyaletown.com/#) is located in Yaletown. Although the prices aren't that friendly (about $5-$6 per pastry cake), the cakes are really quite worthwhile. I lost count of the number of times I visited Ganache and after a while, I can't really remember which cakes I've tried. Therefore, I started to keep track of them:
Some of my favourites are:
1. Matcha-Exotique: I buy a couple to share with my family each time. It has a strong-enough green-tea flavour but not too overpowering (I personally love green tea, and want even stronger flavour if possible)
2. Pur Chocolate: Absolutely chocolate-heaven with a crunchy crust!
3. Marron Cubique: I loveee chestnut. I think this may only have been a seasonal cake, but definitely delightful in its mix of flavours!
Of course, all the other cakes are equally delightful but I enjoy the 3 I listed the most.
Hope you have a chance to try them also!
