It was a drizzling spring day in Williamsburg, Brooklyn, and the “Dirty Dancing” soundtrack was playing in what used to be a mechanic’s garage at 57 Conselyea Street. The place is now a whitewashed room filled with red hearts. The current tenant, Julie Guinta, was clad in a triumphant marigold pantsuit as she welcomed a couple toting paper coffee cups in from the rain. Then she officiated their wedding ceremony in about the time it would have taken their drinks to brew.

After sealing their union with a kiss, the groom’s first words as a married man were, “That was so easy!”

The Sweet Hearts chapel is a new, Vegas-style wedding space in New York built for efficiency, for a pandemic and for Instagram. It’s among a handful of one-stop nuptial shops to open in the city in the last two years. For $650, a couple gets an hour in the chapel, which includes a bathroom and dressing area; a ceremony led by Ms. Guinta, who is ordained through the Universal Life Church, or their own officiant; chairs for up to 10 guests; and a “honeymoon bag” of Ring Pops, T-shirts and recommendations of bars, restaurants and tattoo parlors in the neighborhood. For an additional $500, Edward Winter, a Brooklyn photographer, will capture the event and do a photo shoot against a primary-colored backdrop.

“I didn’t need it to be this big to-do,” said Sim Cheema, 29, who works in finance. She married Daniel Piehler, 31, a founder of the Dubai-based real estate company Nomad Homes, in the chapel on that rainy April 15 afternoon.
