In a city where restaurants chase trends like tech bros chase Series A funding, there's something beautifully stubborn about a place that says: We make one thing, and we make it perfectly.

Holy Nata — the Portuguese custard tart spot — has been turning heads lately, and it's part of a quiet but wonderful tradition in San Francisco's food scene: the single-obsession restaurant. No sprawling menu. No fusion pivots. No seasonal rebrand. Just relentless focus on getting one dish exactly right.

And they're not alone. As one local food lover put it, "Pineapple King Bakery and their pineapple buns are a classic." Over in the Sunset, Rice Roll Express has made a name doing — you guessed it — rice rolls, expressly. These aren't gimmick shops. They're craftspeople.

Here's the thing free-market advocates have always understood: specialization works. Adam Smith wrote about it. Your Econ 101 professor droned on about it. And every time you bite into a perfect pastéis de nata, you're living it. When a business narrows its focus, quality goes up, waste goes down, and customers get something no jack-of-all-trades menu can deliver.

Contrast this with how San Francisco's government operates. City Hall tries to do everything — housing, homelessness, transit, public health — and manages to do almost none of it well. The city's annual budget is north of $14 billion, and yet basic services feel perpetually broken. Maybe our bureaucrats should take a field trip to Holy Nata and learn something about focus.

The specialty food model is also a quiet argument for lower barriers to entry. These are often small, lean operations — exactly the kind of business that gets crushed by San Francisco's labyrinthine permitting process, absurd commercial rents, and layers of regulatory overhead. Every time a great little tart shop or dumpling counter manages to open and thrive here, it's practically a miracle of perseverance.

So next time you're tempted by some overpriced, overhyped restaurant with a 47-item menu and a two-hour wait, consider the little place around the corner that does one thing — and does it with conviction. That's not just good food. That's good economics.
