Georgetown Cupcake brought their pink-powered A-game to Los Angeles on Saturday, not far from where “the world’s first cupcake bakery,” Sprinkles, set up shop in 2005. The chain opened down the street from GC in Georgetown in March 2011.

GC’s fans, some of whom got their first taste of the confection made famous on TLC’s reality-show television show “DC Cupcakes,” braved a steady drizzle and short bursts of heavy rain. Average wait on line: 90 minutes. Sister-owners Sophie Kallinis LaMontagne and Katherine Kallinis Berman posed for pictures and signed books throughout the day.

According to staff, the first to queue up was a mother-daughter pair who arrived at about 8 a.m. from Fresno, more than 200 miles upstate.

“I like the relationship the two sisters have,” said Castellano. “It reminds me of my sister and me. But we don’t fight as much as they do,” she added, referring to the famous cupcake sisters’ quarreling on camera.

Behind Castellano and Spina, a quartet of young adults was holding a geopolitical debate: So, is the District of Columbia a state, asked one of the 20-somethings? What’s Georgetown? Is it like a city in D.C.?

To Kallinis LaMontagne, being based in the District is a source of pride. “We’re proud of where we started. We are proud of our roots as a D.C. small business,” she said.

From its original 2008 shop on Potomac Avenue just north of M Street NW, Georgetown Cupcake has expanded to locations in Bethesda, New York and Boston as well, with plans to open in Atlanta next year. The Georgetown flagship store sells as many as 10,000 cupcakes daily. The company employs a staff of 350.

The L.A. store is located in Mid City between Beverly Hills and West Hollywood at 143 S. Robertson Blvd., where its neighbors include fashion-forward clothiers and expensive boutiques.
