Each episode features Chef Ramsay visiting a different failing restaurant. Each restaurant typically has an outdated decor, poor sanitation, problems with food storage, and a kitchen staff that is either inept, lazy, or uncommunicative. Owners have cut corners by replacing fresh food with frozen processed ingredients. Other owners have refused to take responsibility for their restaurants and have left their businesses running without the benefit of any leadership.
Chef Ramsey typically has the staff clean the restaurant, introduces a new menu, streamlines internal communications, remodels the dining room, lights a fire under the owners, kitchen managers, or chefs, and even assists with advertising.
Most restaurants he's helped have become profitable. At least one has gone belly up due to problems with excessive debt.
