"The New Zealanders have been so amazing in this whole project right from the get-go. It happened so fast and it's been so intense, as much as they've loved the experience, it does rattle you a little bit," said Stewart.
Reviews from local media have been favourable, meaning it's not just the well-heeled sailing crowd that have been flocking in, but discerning San Francisco foodies.
They've had the odd brush with celebrity as well - most notably Tom Cruise, who stopped by the restaurant after taking a joyride on San Francisco Bay with Team New Zealand.
Their casual approach to fine dining has not won over everyone though, and Stewart admits some locals have been confused by the concept.
"Our portion sizes are probably not to the norm of what you'd expect in a pop-up restaurant. But the feedback has been overwhelmingly positive."
Almost on cue, a couple of customers approach Stewart to rave about their meal, before promptly re-booking for dinner that weekend.
"See, that's what I love about this place, people are just so passionate," said Stewart.
