If you do, the chef from Mei Mei is still making them. His wife sells them on the street at the corner of Grand and Christy , 2 PM on. (I was there around 5:30 today). She had the Tainan (southern part of Taiwan) Zhong, the Shanghainese, the Vegetarian black sticky rice zhong, the sweet red bean zhong (which is more of a rectangular shape, like the tamale), the lye-water zhong (where you have to dip into sugar to eat, an acquired taste), and this other one that I'm not sure how to translate but something to the effect of "extra ingredient added". All the savory zhongs are the triangular in shape and $1.5 each. The sweet ones are $1.25 each. I know that the Tainan Zhong is tied with a white + a red string, the Black Sticky rice Vegetarian Zhong is tied with white + black strings. The rest I'm not sure.
I'm uploading a picture of the business card, though it's in Chinese. 3 telephone numbers listed, last of which might be helpful: Tel:718-316 2278;Mobile: 646-275 9306;English:646-812 7064
The Tainan Zhongzi (pork, peanuts, black forest mushroom) had good evenly cooked and mild flavored rice, fresh tasting peanuts that you get from cooking the raw ones which seem to be in season now, and pork that had just the right amount of soft fat. I only wished I had gotten the "extra ingredient added" one, because I wanted a little more filling. It was good neverthelss. Maybe those who have eaten lots of Zhongzi from the former Mei-Mei can tell us whether the taste remain the same or close enough.
