Kevin O’Connell

Executive Chef

Chef O’Connell was born in upstate New York, but his vast life experiences have allowed him to cultivate a career that has spanned almost two decades and has given him a chance to cook on both coasts and work for and with some great talents that have made him the chef he is today.

Kevin O'Connell profile

His father Kevin O’Connell Sr. was a local television personality in the late 80’s and 90’s, working at KNBC and KCBS as a game show host and weatherman. Being an only child, he was introduced by his parents to some of the great restaurants in Los Angeles. At which time his love and passion for food became very evident. His early memories of dining at such famed establishments as Chasen’s, Le Ser, and Mauro’s greatly informed his later career.

Learning his craft came from years of independent study, not having a formal culinary education, and his passion for all things food. From meals prepared by the late famed Chef Giorgio Baldi, to being a judge in a chili cook off with Maude Chasen herself, Chef O’Connell has utilized these unique experiences to create an original and compelling approach to food.

With his family, Chef O’Connell owned and operated a very successful restaurant in upstate New York called O’Connell’s American Bistro. Chef prided himself in the use of local products and a menu that changed seasonally to highlight the area’s bounties at their peak of freshness. The Bistro received both critical and customer acclaim, receiving 4 stars from The Buffalo News on the last occasion they reviewed the restaurant. Chef had the opportunity to host Michael Mondavi for the launch of his new wine, for a private tasting and luncheon. He was also awarded the “Silver Plate” from the Buffalo Food and Wine Society. These awards, coupled with countless donations, and charitable events hosted and participated in is what Chef O’Connell was most proud of during the Bistro’s 8 year history.

In 2012, following a move to Los Angeles, Chef opened 9 Olives, a fine dining restaurant located in the former residence of Charlie Chaplin. Again, he went with a menu that would rotate seasonally and with his relationships with local producers. He received praise from both his customers and the press for his inventive take on California Cuisine. Chef O’Connell had the opportunity to host many events both celebrity and charitable, with great praise from all involved.

Kevin O'Connell cooking

In the beginning of 2014, Chef O’Connell took the position of Executive Chef at the Beverly Hills staple 208 Rodeo. He made his mark with innovative cuisine, and precision-like execution of his very well received menu. Chef would move on to his passion project after 2 years at the helm of 208, and launch his brand of gourmet food trucks and his well received and critically acclaimed pop up series called “Heart & Soul.”

After much success and acclaim in Los Angeles, Chef did as his father did before him, and decided to make his return to Buffalo. His hometown and his family made that an easy decision for him. With his mother, father, daughter and son here in Buffalo, he would decide to embark on his most passionate journey to date and make Greystone his final chapter in an otherwise storied culinary career. Chef O’Connell hopes to bring his vision and talent to those that have loved and supported him throughout his journey.
