Sushi chef retention is the most important risk
Itamae are scarce and not easily replaced. Skilled sushi chefs (itamae) train for years before being trusted with the sushi bar at quality restaurants. Most U.S. sushi restaurants depend on a head chef whose skill defines the restaurant's quality. When that chef leaves, the restaurant's identity often changes overnight. Verify head chef tenure, training, and any employment contracts or non-competes. Plan retention compensation as a non-negotiable part of any deal, losing the head chef can cripple the business.
