Not coming back here ever.
I've been here twice and both experiences were the same - AWFUL.
The line up at this place was massive. It was about a 30 minute wait. For what? Mediocre food...
The service was also super slow. I don't know what's worse dial up internet or Green Grotto's service. Just to order, took about 15 mins and to get your food was another 20-25 mins.
I ordered the Wintermelon black tea and I wanted large tapioca but the server told us that they ran out of the large and small tapioca. Freal? How does a bubble tea place run out of tapioca though... =/ Ugh.
We also ordered a Lychee Green Tea with Mango Jelly, Takoyaki and Braised Pork on Rice with Egg.
The food was overpriced and tasted okay...
Overall, the service and the food was unpleasant. Never coming back.
