Yesterday I had the pleasure of being invited along on one of SF Weekly critic Jonathan Kauffman's many stops through Chinatown. Kauffman is a man with a mission: For a relatively new blog series for SFoodie called "Rice Plate Journal," he's tackling Chinatown's hole-in-the-walls one by one, revealing the mystery within. I love this kind of thing.
I used to work a few blocks from Chinatown during my days at cookbook publisher Weldon Owen back in the mid 90's. I fondly recall the discoveries I made doing just what Kauffman is doing now (though not half as efficiently). I used to spend my lunch hours wandering around and just ducking into any place that seemed busy.
