I originally came to get bbt at The Alley, but seeing the long line, I opted for Chachago instead. Ended up choosing their taro milk tea & original egg waffle.
The taro milk tea (3.5/5) had a layer of mashed taro at the bottom along w/ chunks of taro mixed within. It was nice that they used fresh ingredients, but the layer was too thick (almost like a paste); it didn't mix well and tasted separate from the rest of the drink. It wasn't aromatic either; just okay. For the price of $6.2, I doubt that I'll get it again.
As for the original egg waffle (2/5), the outside was crispy, but the inside was too airy. It was also just straight up sweet; I would've preferred a stronger egg taste.
