Portfolio magazine says party is on … again in San Francisco.

Slide, an unmarked club near the Clift Hotel, is partially owned by Friendster founder Jonathan Abrams.

Ritual Coffee Roasters, in the Mission District, is practically a conference room for local dot-com employees, while venture capitalists mainline their caffeine at cozy Café Lo Cubano, in Laurel Heights.
