This review is for a Large Grass Jelly Roasted Oolong Milk Tea with less ice and 30% sugar. Maybe I don't come here often enough but I'm here almost every other week and literally have not seen a single Light Bulb drink ordered. I also stay about two hours and have not seen it besides in pictures.
The decor is fairly spacious though more tables could easily be added. The larger tables are good for groups, but would also force pairs or smaller groups to sit together, which may not be a comfortable fit.
The service is friendly though as other Yelpers have commented, English is not a strong suit and could cause delays in placing an order, or miscommunication.
The drink I had was too creamy, they could use less milk when putting it together. The taste of the roasted oolong also wasn't prominent, it tasted more like regular oolong black milk tea instead. Free Wifi though, and is a nice place to study/do work on a quiet weekend afternoon. I've tried their Earl Grey milk tea before and that was a bit better, though not by too much. Again, it was the same issue of adding too much milk into the milk tea.
