Today I ordered a "Chocolate Orange" hot chocolate from the large display menu above the ordering area, but the attendant who barely spoke English seemed very confused by my request and made me a regular hot chocolate. Though not what I ordered, it was very good.
Unfortunately I had a similar order fulfillment issue when I tried this coffee shop inside Royal City Centre several years ago. At that time I ordered a macha tea and after specifically asking if it was unsweetened and being assured that it was not, I received what turned out to be a macha tea made from presweetened powder. I remember that the attendant that day also could not speak English well.
The menu lists multiple exotic hot beverages, but I am now convinced that the attendants are not familiar with them. Stick to plain coffee, tea, or hot chocolate if you purchase from this mall vendor.
