BBT is a sporadic treat, and 'The Alley' has been on my list for a while. I had the popular Alley Trio Milk Tea (milk tea with tapioca, aloe and jello) with less ice, half sugar and in the large size. The first sip of tea showcased how fresh their tea is. It was fragrant and had a great aroma. The cane sugar highlighting the flavor without making it too sugary, which is my usual issue with BBT. I was impressed by the tea quality and how they kept it as the center-point of the drink. Personally, I would have preferred the aloe or the jello to be switched out for something else (like grass jelly?) since their texture was so alike and I couldn't tell them apart.
The space is meant for more grab-and-go. There is limited seating (two bar areas, three 2ppl tables and a larger sitting area around a tree). You may get lucky and grab a table, but expect to be patient for a seat.
A side observation. This location seems like a popular destination for first dates. I was here on a Sunday afternoon and there were two first dates going on (easily spotted by a guy arriving way early and staring at the door a lot, a girl arriving later and awkwardly saying hi, and the subsequent first-date interview process). It was cute to watch.
