The well known tea set, Pineapple bun and Hong Kong style milk tea, is very delicious. I regularly go this cafe and they still keep the quality level. However, as a non-chinese tourist, it is quite hard to communicate with the waiter as they have difficulty to speak English.
The food are delicious with reasonable price.
Universal theory: if you can't speak and read Chinese, look around what the locals are eating and order most.
