The Kardashian sisters are staying drama-free in N.Y.C.! Kim, a pregnant Kourtney and Khloé Kardashian stepped out for a family meal at New York's Hurricane Club with their significant others – Kanye West, Scott Disick and Lamar Odom, respectively. And Rob Kardashian didn't miss out on the festivities at the Polynesian-themed eatery, either.

"They all seemed to be in a very relaxed, calm mood," a source says of the large group, which also included Kelly Osbourne. The group shared an array of appetizers (known as "Pupu") and cocktails, including one drink for the group that was served in a watermelon. "It seemed like a nice family dinner to start the week."

According to the source, at various points throughout the evening, they would all get up and pose for their own photos. Kim and Kanye were smiling together, and he doted on her from his seat at the head of the table. Khloé and Lamar, who just announced they were taking a break from their reality show, were more subdued but still seemed to be having a good time together. Says the source: "[They were] sitting close – whispering."
