Kyle Richards got her fishy fill when she recently stopped by Koi restaurant in West Hollywood.
Coming out to celebrate the birthday and launch of fellow Bravo TV personality Patti Stanger's new site PattiKnows.com
, Richards was offered an array of sushi options, along with pan-seared dumplings and steak skewers, once she mentioned she was "starving."
"Kyle came with [Flipping Out
's] Jenni Pulos," an onlooker tells PEOPLE. "Kyle didn't walk the pink carpet at the event. She said her husband would be joining her later, but she didn't want to wait for him, so she and Jenni were immediately seated at a V.I.P. booth. Her husband never ended up coming."
As the ladies sipped on white wine, Richards's fellow Real Housewives of Beverly Hills
costars Lisa Vanderpump and her hubby Ken Todd joined the gals in their booth.
"They all continued to eat and drink together," the source says. "Patti came over at one point and gave big hugs to her guests while they showered her with birthday wishes. Kyle and her crew stayed for about an hour and a half. They seemed to be enjoying the party, but definitely kept to themselves." – Dahvi Shira
