Ryan MarcouxExecutive Chef
Ryan Marcoux is the Executive Chef of Grill 23 & Bar, Boston’s premier steakhouse and seafood grill.
Chef Ryan Marcoux has more than a decade of culinary experience working in some of the most notable kitchens in the area. Most recently, Marcoux was the Executive Chef at Boston Chops under noted chef Chris Coombs. Marcoux also spent time working as the Chef de Cuisine at Parsnip in Harvard Square which was known for their refined and elegant dishes and he was one of the opening chefs at Sel de la Terre under James Beard Award-winning chef Frank McClelland. He still considers McClelland to be one of his mentors.
Marcoux spent much of his life traveling and living in different countries which helped fuel his interest in cooking. As a child, he spent time in the British Virgin Islands and lived on St. Thomas.
It was when he went to Italy as a teenager that he began to think seriously about becoming a chef. He later traveled to Australia where he visited vineyards and farms which gave him a deeper understanding about the correlation between food and wine. He is a graduate of Johnson & Wales and lives in Worcester with his wife and children.

Chris Himmel of the Himmel Hospitality Group grew up in the restaurant business. The Himmel family owns and operates four of Boston/Cambridge’s most successful and respected restaurants: Grill 23 & Bar, Harvest, Bistro du Midi, and The Banks Fish House. Chris has been a fixture at the restaurants most of his life; first at Grill 23 & Bar, one of the country’s top steakhouses; next at the iconic Harvest in Harvard Square, where New England farmers and product have been the culinary inspiration for over 45 years; at Bistro du Midi, a French bistro with coastal New England influences; and most recently at The Banks, a revival of the New England fish house.
Chris’ philosophy is grounded in hospitality and product. “At our core is the commitment to the finest ingredients and the best trained staff,” Chris explains. A graduate of the prestigious Cornell School of Hotel Administration, Chris set his sights on learning from the best in hospitality, training under Danny Meyer and Chef Thomas Keller. Running the three Boston/Cambridge restaurants owned by Himmel Hospitality Group, Chris brings a deep passion for product and hospitality to each of the restaurants.
A supporter of the Boys & Girls Club, Chris has invited youth members to come in and cook their own garden-grown product and experience the inner workings of restaurants. “It doesn’t get any better than this,” smiles Chris. “Food brings people together in a community. We are happy to bring people to the table.”

Jeff Osowski oversees the restaurant’s daily front of house operations, and works to ensure a memorable dining experience every step of the way from the door to the kitchen.
A native of Connecticut, he has worked in almost every position in both front and back of house since starting in hospitality at age 15. Early in his career, he pursued his passion for art and music as a recording musician, performing throughout New England. While studying theatre and arts in college, however, he decided to pursue his love of hospitality full time and has since spent his entire career in hotels, casinos, catering and restaurants.
In 1992 he joined Foxwoods Resort & Casino where he worked as a server, opening three restaurants over the course of eight years. In 2000 he transitioned to Morton’s Steakhouse where his management experience began. He served as Assistant General Manager for one year and General Manager for two years, during which he managed three different cities including Washington D.C., Boston, and Hartford. In 2004 he received the “Team Excellence” Award out of more than 60 candidates due to his positive work environment and low percentage of employee turn-over throughout the entire company.
In 2008 he took a position at Grill 23 & Bar as a server. After more than seven years at the Himmel Hospitality steakhouse, Osowski moved to sister restaurant Harvest, located in Cambridge, where he served as Assistant General Manager before being promoted to General Manager.
