During Monday's special Keeping Up With the Kardashians episode, the family celebrated Disick's Japanese restaurant, RYU, opening in NYC. A fan tweeted Kourtney after the show, "You looked stunning at Scott Disick's RYU opening doll! Love you!" She responded, "Thank you! Excited to go back and eat sushi!"

At his opening party on April 23, Disick, 29, told Us Weekly, "I have always wanted to open my own place . . . and [the Meatpacking District] seemed like the hottest place to be right now. There didn't seem to be any Japanese restaurants in the area so I wanted to fill that spot."

Pregnant Kardashian, 33, had to skip the sushi menu at the time, but now baby Penelope has finally arrived. Kardashian and Disick have been together for five years and are already parents to 2-year-old son Mason.
