Market St's traffic-stopping 1937 Mayan deco landmark was built to accommodate 300 wholesale furniture design showrooms – but a decade ago, less than 30 remained. The city offered tax breaks to Twitter to move here from its South Park headquarters, and after a $1.2 million LEED-certified green makeover, including a rooftop farm, Twitter nested here. Only employees can access Twitter's free video arcade and Birdfeeder cafeteria, but ground-floor public Marketplace offers 22,000 sq ft of local gourmet fare.
The upscale oyster bar overlooking a gritty street corner is a definite clunker, but the Four Barrell coffee kiosk, multi-culti food stalls and central wine bar are hits with techie lunch crowds. Tweeting about your meal here seems uniquely appropriate, but consider what the emergency sign says upstairs: 'In case of fire: exit building before tweeting about it.'
