This city's politicians haven't just served as cheerleaders for the tech beachhead transforming mid-Market, they've provided covering artillery fire in the form of lucrative tax breaks. There is one business, however, local leaders have striven to keep out, even though it easily does something many of the city's tech darlings cannot do — turn a profit. That business is McDonald's, which aims to dispense Big Macs and fries from the erstwhile site of a vegetarian restaurant (horrors!). The Golden Arches may yet have to seek a less contested site to add to its billions and billions served. But, fry fanatics, worry not: Another outlet is on Market Street a mere 0.2 miles away.
