Go to Golden River on Geary @ 23rd ave in the Richmond. You can order off the Dim Sum menu, so you don't have to wait for what you want. Get the Shangai Dumplings, Sui Mi, Stemed pork bun, shrimp with parsley...all yummy and very reasonably priced
I have liked Golden River for many years, and it seems like they change ownership often. Still, it is a nice low-cost alternative to Ton Kiang, which is often a lot more crowded. The food isn't fantastic, but nothing has been bad and I felt it was really quite good for the money on the times I have been.
