Given the number of places to eat in the SFO Terminal (although I do not know how many are open at that unholy hour), I would probably not bother getting a day pass for your layover. It should be easy enough to find an empty gate to sit for a while before your flight. Of course, you could always see if another FTer could guest you into one of the clubs.
