At the start of his career, Solomonov moved back to the United States to attend culinary school at the Florida Culinary Institute in
West Palm Beach. He then moved to
Philadelphia,
Pennsylvania to cook Italian cuisine at Chef Marc Vetri's upscale Italian restaurants. Afterwards, Solomonov took a job as a chef at Marigold Kitchen, owned by businessman Steve Cook. Cook and Solomonov then opened the upscale Mexican restaurant Xochitl and later co-founded the restaurant group CooknSolo. It was only three days before David’s release date from the Israeli army, after three years of mandatory military service. David was not supposed to be on duty that day, but he volunteered to replace a fellow soldier who wanted to go to synagogue for Yom Kippur; he was 21 years old. David's death was one of the main factors that influenced him to change his focus to
Israeli and
Jewish cuisine. With the support of an investment banker turned chef Steve Cook, Solomonov opened
Zahav in 2008. With his business partner Steven Cook, Solomonov is co-owner of several Philadelphia restaurants: Dizengoff, vegan
falafel restaurant
Goldie, Laser Wolf, Abe Fisher, Percy Street Barbecue, and
Federal Donuts, a fried chicken and donut chain. Having participated in the South Beach Food & Wine Festival in 2013, Solomonov was able to bring Percy Street Barbecue to South Florida. Bill Addison, writing for
Eater Philadelphia, called Chef Solomonov "the Genius of Modern Jewish Cooking" after eating at Abe Fisher, Dizengoff, and Zahav. Solomonov also spent a period of time consulting for David Magerman's, now closed, and Citron and Rose, a certified Kosher meat restaurant on the Main Line in
Bala Cynwyd, Pennsylvania. In 2015, Cook and Solomonov published a cookbook based on their restaurant Zahav.
Zahav: A World of Israeli Cuisine was nominated for a
James Beard Foundation Book Award in the International cookbook category. Its recipe for
hummus was chosen as "2015 dish of the year" by
Bon Appétit. In 2025, Solomonov and his partner Steve Cook launched Aviv, an Israeli fusion restaurant, in
Miami Beach,
Florida. They also launched their Zahav hummus into national retail stores, including
Whole Foods and
Target. ==Awards==
