This sign appeared almost a year ago after I shot a photo of a man eating an ice cream cone there. I have shot this sign many times since, but always found something else better those days.
I know of no law that says I cannot photograph whatever I want on a public sidewalk outside of a storefront convenience store.

John, I was curious. Just Googled the CA. penal code they mention: "California Penal Code 602 PC prohibits the crime known as criminal trespass. Put very simply, you may commit the California crime of trespassing when you enter . . . or remain on . . . someone else's property without permission or a right to do so." They must think the sidewalk/street in front of their place is their private property. Anyway, Good shot.... and keep going for it.
Some people certainly want to claim rights that are not theirs. I would be tempted to photograph their place every single day. But they would be well within their rights to refuse to serve you.
In Canada, and I think in the U.S. also, a photographer may legally take a photograph of anything he or she can see while standing on public property like a sidewalk. For example, animal rights friends of mine may legally photograph a slaughterhouse if they can see over or through the fence surrounding it. I have seen a documentary on this, in which photographers are urged not to be intimidated into not taking pictures which they have a perfect right to take.
