This seems like any standard bubble tea shop downtown with standard offerings of simple meals and sweets. I didn't see anything to differentiate on their menu, and that's fine. Bubble tea & desserts are always welcome in my books, especially in the downtown core where late-night non-bar options are few and far between (though improving!).
However, opening weekend pains seem to be affecting this place. Of three orders, two were wrong, even when taking the time to point out and correct one item in question during the ordering process. The other drink came with un-asked for tapioca and we were still charged for it when we pointed this out to the wait-staff.
Given that there is so much competition for bubble tea in general and nothing to set this place apart, I'm not sure that I'd return after the less than stellar service and response. Their late-night hours are a lure, but HiTea should take the time to train and educate their staff so that their staff - their front-line - can effectively address issues that arise and be an effective ambassador for their brand. A less than grand opening, unfortunately.
After all the errors, I did chuckle when our waiter came by later to point out that we could like their Facebook page and get a free regular milk tea with tapioca.
