Tuesday’s nights Prime KO opening party saw an eclectic mix of celebrities. We caught up with Jamie-Lynn Sigler (“The Sopranos”), Ramona Singer (“The Real Housewives of New York City”) and Eli Kirshtein (“Top Chef: Season Six”) to talk restaurants.

Self-described foodie Sigler named Keith McNally’s rustic Italian West Village restaurant Morandi as her favorite NYC dinner spot. “I also love brunch at [Norma’s] at Le Parker Meridien,” she said. Sigler also admitted to be a fast-food junkie. “I eat at McDonald’s about twice a week.”

Real NYC Housewife Singer told us that her sweet tooth some times guides her to Crumbs on 78th and Third Avenue for breakfast. “I love their small vanilla cupcakes with chocolate frosting. Sometimes I pick one up on my way to work,” she said.

Kirshtein said he’d love to open the space, either on the Bowery or in the West Village, at some point early next year.
