all i needed was my passport, an address, and two passport pictures. they automatically said it would be ready in three days, and said they couldn't do it faster (though might be able to if your flight is soon).

note the visa hours: M-F 0900-1200, 1300-1400.

you can take a few buses from 菊花村 to right near the consulate 众_商务. i took the 5 to and then the 170.
