Chef/Partner Mark Dommen

Mark Dommen is a unique talent who has spent more than 20 years in the kitchen. After years of classical training with some of the world’s most eminent culinary masters, Dommen’s move to head One Market® Restaurant in 2004 marked his exciting return to the San Francisco dining scene. His modern take on American cuisine earned the restaurant a Michelin star in 2008-2012 and a 3 ½ star review from San Francisco Chronicle critic Michael Bauer. Dommen was also named a 2007 “Rising Star”. Outside the restaurant he actively participates in numerous charitable and community endeavors.

Dommen’s contemporary, seasonal American fare developed through his work in some of the world’s most distinguished restaurants. His career began at Fleur de Lys in San Francisco, where Chef Hubert Keller became Dommen’s mentor in the art of contemporary French cuisine. Dommen later spent four years in New York, honing his craft with one of his largest influences, Gray Kunz at Lespinasse and also with David Burke at Park Avenue Café. By the time he opened Palladin as Sous Chef for the legendary Chef Jean-Louis Palladin, his immersion in the art of French cuisine was well advanced. Dommen was next invited to join Julia’s Kitchen in Napa Valley as the opening Executive Chef. While he was at the helm, the restaurant was named one of Esquire magazine’s “Best New Restaurants.”

Dommen describes his approach to cooking as “blending the freshest, seasonal ingredients from California, while using the classic French techniques I have honed from my previous experiences.” His seasonally changing menu includes inventive farm-fresh dishes such as Lightly Smoked Tasmanian Trout Mi Cuit with potato rösti, organic chicken egg and pancetta vinaigrette; Dungeness Crab with green apple water and jalapeño sorbet; and Bacon-Wrapped Pork Tenderloin with dandelion “persillade,” salsify and natural jus.

“I truly enjoy experimenting with the freshest of produce, seafood and meats to create entirely new and unexpected dishes,” says Dommen. “I make a point each day to ensure that the menu is a reflection of the finest raw materials prepared in a unique, delicious and artistic way.”

’Some of Dommen’s favorite dishes to make when not in the kitchen at One Market Restaurant include pizza and barbequed beer-can chicken cooked over apple wood chips. He lives in Napa with his wife and two daughters and enjoys skiing, golf and fishing in his spare time.

GM/Partner Lorenzo Bouchard

At One Market Restaurant in San Francisco, Lorenzo Bouchard works to ensure that the restaurant upholds its commitment to providing an unparalleled dining experience for its guests.

“With a history of serving quality cuisine in an ideal city location, One Market Restaurant has been a popular force on the dining scene since opening,” says Bouchard. “One of the most important aspects of my job is to make sure that we continue to surpass our guests’ expectations and raise the bar in terms of excellence in cuisine and service.”

Lorenzo got his first taste of the culinary world when he was waiting tables in college and became entranced by the bustling excitement and activity. He later worked as a waiter under Chef Dennis Foy at The Tarragon Tree in New Jersey and as a food runner then waiter and then manager under Chef Michael Roberts at Trumps (named after the wild cards in Bridge, not the former occupant of 1600 Pennsylvania Avenue) in Los Angeles. Lorenzo was the opening Manager of One Market in 1993 and served as General Manager/Partner from 2000 to 2008. After a two year Southern California sabbatical, he returned to One Market in March 2010.

“The most rewarding aspect of my position is receiving a sincere ‘Thank you’ from a guest for all of our collective efforts, and knowing that this guest will share their experience at One Market Restaurant with their friends and family.”

Bouchard’s civic involvement has included a stint as a Director of the Golden Gate Restaurant Association and his participation as a founding member of the Steuart Street Restaurant Row Association. He also served two terms as a member of the Board of Directors for San Francisco Travel.

In his spare time, Lorenzo loves spending time with his spouse, Fred and their special needs rescue black Labrador Retriever, Jett. Lorenzo is working as well on catching up on the family history he’s recently discovered via 23andMe. He met his paternal biological family in 2017 including his father who owned and operated a successful NY-based multi-national fruit and produce import business and was a master home-chef and a grandmother who was the first female chef admitted into a Manhattan chef’s labor organization. Clearly the apple didn’t fall far from the tree.

Bar Manager Oscar Davila

Though born and raised in San Antonio, Oscar has lived in San Francisco long enough to view himself much more as a Californian than a Texan. Oscar holds a BA in Dramatic Literature from Southwest Texas State and did post-graduate work in the UC-Santa Cruz film department and still considers himself a proud UCSC Banana Slug!

His first taste of the hospitality life happened during a semester abroad in London and would continue upon his arrival in San Francisco working at several well-known spots including here at One Market Restaurant, Akimbo and Postrio. Oscar then set his sights on wine and received his Court of Master Sommeliers certification in 2012 and immediately set to work as a somm and wine buyer at La Mar and used his extensive and ever-expanding wine knowledge during his general manager tenures at Sous Berre, Cala and Sorrel.

But Oscar wasn’t quite done with One Market Restaurant as he returned post-pandemic to his position as Bar Manager and he believes the restaurant is either insane or of excellent taste to bring him back for a fourth time! The restaurant falls squarely in the camp of the latter.

In his spare time, Oscar is a British-Bake Off worthy home baker with a rapt at-work audience as well and he takes special pride in his parenting skills as devoted dog dad to his Schnauzers Hank and the recently departed Cowboy.

Oscar considers OMR his “second family” and the feeling is decidedly mutual.
