My husband and I will be flying in around 9:30 on a Friday night. Any good eats near Nob Hill, where will be staying. It'll probably be 11:00ish before we made it anywhere. Something relatively close (though a short walk or cab ride is fine), casual and good.
Also, for our Saturday night dinner, we're trying to decide between Gary Danko, Aqua, Delfina, and A16. What would you pick? Any others that need to be added to our short list? We only have two nights in San Fran.
