Ah, the perfect San Francisco date.

Nothing says love like a sourdough bread bowl filled with New England clam chowder, a few hundred barking, stinky sea lions, and a blue square (aka registered sex offender) escorting an underage girl through the biggest tourist trap in the city.

If you thought that buskers jumping out from behind garbage cans were the scariest thing about Fisherman's Wharf, now there's something else to keep you away from the area. Could Fisherman's Wharf be the new hot spot for sexual predators?

On Sunday, a 15-year-old girl, missing from her home in Sacramento since Thursday, was found with registered sex offender Anthony Butler, 31. (He does not come up on a search of Megan's Law.) They were found at the wharf after the girl made a phone call to her parents. The call, we guess, was traced by police. The lightning-fast cops found the pair together, took Butler into custody, and sent the girl to a local hospital. Police figure the two met online, even though the girl's family does not have a home computer.

So why, of all places, did Butler take the girl to Fisherman's Wharf? If only he had asked SFist for some tips beforehand. I'm sure our readers could have recommended some better alternatives. Why not take your date down the real crookedest street in San Francisco - Vermont Street in Potrero Hill. Or what about grabbing a burrito at Papalote in the Mission? Even blue squares need to know that there are options.
