I am shocked you never heard the old quote attributed to Twain: The coldest winter I ever spent was a summer in San Francisco.

Not true that Twain said it, per snopes: http://www.snopes.com/quotes/twain.asp

But, it is true that there are many cold, foggy summer days in the City by the Bay!


One or two other people have mentioned Cavallo as well.

Not in San Francisco, but as close as you can get! Plus Sausalito / Muir Woods / Stinson Beach are nearby.

My kids always liked going to the lighthouse when they were the age of your child too: http://www.nps.gov/goga/pobo.htm

For what it's worth, Cavallo is highly ranked by T&L readers. I have never stayed here, but it is one of our go to spots for fabulous dinners.
