This is a review more so to warn fellow Yelpers about my experience. It wasn't a horrible experience, but definitely not one that I want others to have.
I arrived at about 9:30 PM on a Saturday night and there was a long line going out the door. We probably waited 25-30 minutes for the line and our order. The decor was cute with references to Harry Potter such as the subtle link to diagon alley (da symbol on the drink) and the Horcrux of the deer was interesting.
We were offered a sample of the Royal No. 9 milk tea, which was actually very good. The hint of blueberry taste is very refreshing and really makes it one of my favourite milk teas that I have tried. However, given that it's Saturday, it would be unfortunate not to try the Black Sesame Deerioca (hand-crafted tapiocas) that they offer only at this time. I was told that you have to order the Jasmine Milk Tea for the Deerioca because it doesn't go with any other drink. And so, I did. It was expensive for a small size (more than $7 after tax).
So I got the drink and very excited to try it. The Jasmine Tea was okay, pretty fragrant - but the Royal No. 9 was miles better. The tapioca though - while it had a decent taste of black sesame - the texture was not what I expected. It was more doughy than chewy. I would have much preferred my friend's No 9 Milk Tea with their normal tapioca. The texture is definitely not what I was expecting and was quite put off by it.
I was peeved that the Deerioca - their major selling point - was not able to deliver and made me choose an inferior drink compared to their other options.
