I just had to give a thumbs up to the moon cakes made by Dick Lee's in SF Chinatown.
I went around various bakeries that made their own moon cakes and found Dick Lee's to be the tastiest and freshest. I think they make them every night. Last Saturday I purchased a box and the lady behind the counter told me they were made last night. For a box of 4 it's $11.50, mix and match any flavor. The price goes down if you buy more boxes. I got the white lotus with two yolks and the red bean with two yolks. The crust is tender and slighly crumbly, not thick and starchy. The filling is smooth and sweet, with the sweetness off set by the salty yok in the middle. It's so good I think I'm going back this weekend to buy some more before the season is over!
I've also tried Napolean's Bakery, Tung Kee, Mee Mee, and one other bakery on Stockton (forgot the name). But none of them measured up to Dick Lee's in my opinion, and they cost more, averaging 3 to four dollars each.
