Bakeries wouldn’t seem the obvious place for one-percenters to spend their dough.

But Sant Ambroeus is not your average bake shop. Founded in Milan back in 1936, the traditional Italian eatery has spread across tonier tri-state ’hoods — Southampton, SoHo, Madison Ave. — to become the pastaria and pasticceria of choice for major fashion, media and money-makers.

Everyone from Valentino and Nick Jonas to Gigi Hadid and Taylor Swift have been spotted at its 4-year-old Lafayette Street outpost.

Gherardo Guarducci, co-founder and partner of SA Hospitality Group, which owns Sant Ambroeus, oversaw its most recent debut — on sleepy Third Avenue and 66th Street. It’s an interesting choice, but the area is now more desirable with the expansion of the Second Avenue Subway — and has already proven a hit for nearby fancy French boulangerie Maison Kayser owned by Eric Kayser (which boasts bakeries from Colombia to The Congo).
