Are you talking about the "sugar water" with the older couple? They open up a store la close to a year ago, it's on Saba Road near Richmond Public market, across from a Vietnam noodle place.
Yeah I know the most famous one closed down last year, but last year at least some other store had chinese dessert...I think it was a guy with fried ice cream too. But this year even he is not here...so no more chinese dessert period
