Patisserie Gateau is really another Chinese Bakery that selling Chinese buns and pastry along side with HK style milk tea and other drinks.
Aside from the usual pineapple buns and BBQ porks buns, you can also get a drink and bun/sandwiches from $1.80, great afternoon tea options.
Patisserie Gateau does carry some European style pastries. It is just a looks and feels a little sketchy as a Patisserie :P.
