“Ambition isn’t something that’s in short supply these days at 165 O’Farrell St. in Union Square. The six-story brick building is in the throes of a multimillion dollar renovation effort. Once complete, its name will officially be ONE65, and the 25,000-square-foot interior will be home to ONE65 Patisserie, ONE65 Bistro, ONE65 Lounge & Bar and a fine dining restaurant called O’. Suffice to say, ONE65 might be San Francisco’s most ambitious hospitality project of 2018.”
