As you step into the Nan Feng Ice Shop on Xi Gang Street, the old, vintage refrigeration machines hum along, exuding the nostalgic atmosphere of traditional ice shops from the 40s and 50s. The thick, heavy ambiance transports you back to your childhood, a joyful time of eating frozen treats and balloon-shaped ice cream. Nan Feng Ice Shop also sells red tea, which is unique in that it's brewed and then placed directly in the freezer to chill, rather than being mixed with ice. The result is a rich, satisfying flavor that's both refreshing and quenching.
