Happy Birthday Donut Master! I understand San Fran is undergoing something of a Krispy Kreme shortage.... Have a semi-skimmed ultra-lite no-caf bottle of JD on me.
Bit late for breakfast but if you are staying there tonight as well then go to the Taylor Street Diner on Taylor Street just south of Ofarrell St tomorrow morning and get the steak and eggs (out of this world) - and it will be about 5 minutes walk from the kind of establishments that I suspect you will be frequenting tonight!
