late cafes

[allli.livejournal.com]

i need a place outside of my apartment to get work done in the evening-times.
how late are the cafes open around davis, porter and harvard?

i know of:
true grounds- closes at 8 or 9
diesel- open late but crowded etc
someday- hours??
starbucks near porter- open late, but it's starbucks
simon's near porter- i love it, closes at 9
anywhere else near porter?
tealuxe in harvard- hours?
dado tea in harvard- hours?
bubble tea shop in harvard- open late but loud and bright
others?

thanks.
