During the grand opening last Saturday, the line snaked down Mercer Street in SoHo, as fans and freeloaders alike waited for the chance to score a complimentary cupcake. (As co-owner Sophie LaMontagne noted, customers at the two Washington area shops could get in on the freebie action, too.)

Seems like old times: The line on opening day in Soho looked a lot like Georgetown Cupcake during the weekends in Washington. (Georgetown Cupcake)

“We almost ran out, and we never run out,” Katherine Kallinis added. ”The line went down to Prince [Street], and we were freaking out.”

By the end of Day 1, the sisters estimate they sold more than 10,000 cupcakes.

“We’re getting Georgetown volume,” Kallinis said.

So, after a few days in business in Gotham, what’s the difference New York and Washington?

“There’s a lot of deliveries here,” Kallinis said. “We own an apartment here, and I realized that everyone uses FreshDirect to get groceries delivered.”

“In D.C., we get a lot of deliveries, too,” added LaMontagne. “Expectations for deliveries here are different. They usually expect . . . to have them delivered immediately.”
