I used to get these amazing mushroom piroshki at some place on Geary, now gone. The mushroom filling included some sort of vermicelli or rice noodles - little clear strands of something. Anyhow, I've been longing for really good piroshki of any kind. I tried some at Moscow Bakery on Geary, but found them really heavy, doughy, and oily. They made me a little ill. And they were long, like bagel dogs, instead of the oval piroshki of my youth. Can you guide me to a good one?
