CHICHA San Chen is a bubble tea shop at Compass One in Sengkang, Singapore, rated 4.8 from 1,026 Google reviews.
A good bubble tea depends on three things: the tea base, the sweetness, and how fresh the pearls are. Tapioca pearls harden as they sit, so small batches usually taste better than pearls left in a warmer for hours. Start with a lower sugar level than you expect, since syrup can drown out the tea. For a first visit, a classic milk tea with standard pearls shows you the base before you try the seasonal flavours.
Compass One gets busy at weekends, so it helps to decide what you want before you reach the counter.
