Starbucks
The coffee is very similar but there are very minute differences, I find the half sweet coffee Machiato in Toronto is sweeter than the normal Machiato in Hong Kong. Otherwise, the taste of the coffee seems very similar. The biggest difference is the services Starbucks offers: Coffee Delivery. Imagine this in Toronto...Late night coffee break while pulling an all nighter! Crazy stuff.
Hagen Dazs
Hagen Dazs is very popular in Hong Kong, enough to warrant a cafe for it. They serve some amazing high tea stuff, including an ice cream chocolate fondue. In addition, they have amazing flavours of ice cream as well, like Tiramisu.
