In empty-calorie celebrity news, noted father/crooner Kanye West was spotted gallivanting about town over the weekend. Was he here for the annual Living Sober conference? We should say not! But while he was here, he did visit a few notable locations with equally notable people. Let's begin...

On Saturday, Yeezy and Instagram cofounder Kevin Systrom checked out Park Tavern, younger sister of Marlow in SoMa). According to our sources, the duo dined on pancakes and discussed Instagram for most of the meal. (The artist, if you recall, is openly technophile.)

Later in the night, Kanye was off to Hayes Valley to check out Smuggler's Cove (voted best bar in San Francisco by SFist readers). Above: Mr. West, sporting a black hoodie, joins birthday boy horralltiki for an impromptu photo op.

And there you have it.
