There's a new Shanghainese Restaurant on 16th and Geary called Old Shanghai (I believe - it has a green awning) that is where Mike's used to be. The xiao long bao (steamed dumplings) are the best I've had outside of the famous Ding Tai Fung in Taipei. The outer skin is super thin, and the inside is juicy with broth flowing out when you bite into it.
Dumplings 101: Make sure you eat them while they're hot since the outer skin tends to harden when it comes in contact with cooler air, but be careful not to burn yourself since the broth inside the dumpling is piping hot. Use your soup spoon to hold the xiao long bao as well, since it would be a tragedy for the broth to fall on to your plate.
I've had both lunch and dinner there. For lunch, the thick noodles are good, but I wouldn't order the chao neen gao again. The potstickers are good too. The lion's head (really just pork meat balls) have a delicate taste, uniquely done in a tasty broth. For dinner we had the cabbage with preserved ham, which wasn't not the menu - delicious, a deep fried pork dish - delectable, their preserved cabbage rice, and a ton of xiao long bao.
The service is decent and helpful and the atmosphere is nicer than your average Shanghainese restaurant.
I would really like to see this restaurant succeed so give it a shot!
