Definitely do not come if there is a line up - they are slow even with a short line up, so I'd imagine a long lineup to take extremely long. Other than this, the service is good as they always have samples and are willing to take the time to explain the different drinks to you.
I've tried several different milk teas here -
Royal no.9 milk tea - this has a slight hint of blueberry flavour, which makes it quite unique. Most of my friends seem to like this the best but I found it to taste generic with an added blueberry taste. I am a bit of a tea person so I like my teas a bit stronger.
Iron goddess milk tea - this is my favourite tea (Iron Buddha oolong tea) so I didn't need any gimmick for it to be my favourite drink. I like that the distinct tea taste came across well and mellowed out with the milk/cream that they put in the drink. Overall, quite good for a bubble tea for someone who enjoys their Chinese tea!
Jasmine milk tea - I think this is the same as the Iron goddess milk tea except they used jasmine tea. The tea is quite fragrant, has a sweet aroma and is refreshing. I think the taste of jasmine comes across the bubble tea quite well. The only thing is I like Iron Buddha Oolong a lot better!
I've yet to try the hand made tapioca as they only offer it during very limited times and hours but I'd love to try!
