My top two:
Chef Jia, Broadway/Kearny. My favorite Chinese food in town (Tai Chi is a solid second). Nice irony factor given location (Nanking is next door, never understood why people like that place).
Darbar, Polk/Pine. Been mentioned here before.
I leave big tips at both these places...food this good at nearly McDonald's prices makes me almost feel dishonest when I get the bill.
