Restarting the best study-friendly restaurants, coffee shop, etc discussion for late summer 2013 (as places change/close) but moving the center of discussion to the USC health science area of LA - just east of downtown. However, any radius from there to Pasadena, Los Feliz, etc is fine.
I prefer large tables, quieter side, outlets (although getting better battery life with Surface RT), and Wi-Fi (ideally free). Excellent coffee and non-greasey food preferred.
Open until 11 pm ideal.
Also where to go on Friday / Saturday nights when the library closes early?
