The space itself is amazing. There's artwork suspending from wires above in a 2 storey high open ceiling. It's flooded with sunlight during the day because of the all glass enclosure.
The drinks are good, there's an extensive menu of drinks with occasional features/limited edition offerings. *Another reviewer mentioned fresh milk tea vs milk tea. Bubble tea is usually made with milk powder so fresh milk literally means milk like you buy in stores.
The food is hit or miss. I'd say you can't really go wrong with any of the fried snacks they offer. I once ordered deep fried soft shell crab with dry noodles. The crab was great, the noodles were definitely dry... too dry. Their chicken was fine and their rice with mince pork was okay as well. I wouldn't recommend a meal here.
Service is alright. The workers are usually able to understand and communicate just fine, I will say they sometimes confuse my order but they fix it promptly, no questions asked.
Also I wouldn't study here, there's a 2-hour seat allowance. I've never seen it enforced but it's probably better not to risk it.
