Our pat-bing-soo: soft shaved ice (hidden at the bottom), sweetened red beans, diced melons, ground peanuts (I think), mochi (the few white things), green tea ice cream, and a bit of condensed milk. Very good. There was a nice texture contrast among all the ingredients. The flavor mostly came from the red beans, which were of good quality ("sweet and glutinous," Di Yin said). The mochi, by the way, I wouldn't have noticed if Di Yin hadn't pointed them out. Di Yin said the mochi wasn't as good as the mochi at Charmant (a place in Shanghai that serves a vaguely similar dessert; see this visit for example), but the red bean was better.
E approved of the dessert, saying, "I'll put this in my regular rotation."
