Not a particularly Chow-ish development, but since new eateries in Chinatown are a fairly rare occurrence it's definitely worth noting. Yummy Dim Sum and Fast Food has opened up at 930 Stockton St., the former site of Fortune Star Cafe since the 1990s. I'm not sure if this is related to the other Yummy places that have opened up in Chinatown recently, though they do have the Mexican bun like Yummy on Jackson does. Yam buns, too. Chicken buns for 50 cents are a good deal as the breading is pretty good.
