Mr Hamburger SA, operating as Mr Hamburger SA w restrukturyzacji, is a Poland-based foodservice company that specializes in quick-service restaurant operations, fast-food retail, and casual roadside dining concepts. Founded in 1990 and headquartered in Krakow, Poland, the company provides food and beverage services targeted at retail consumers, commuters, and travelers across Poland, with historical regional strength in Upper Silesia and transit corridor locations.
The company's core product and service portfolio includes classic hamburgers, cheeseburgers, and specialty beef burgers; breaded and grilled poultry burgers; frankfurters, hot dogs, and specialty sausages; meat kebabs and gyros dishes; stuffed tortilla wraps and pita sandwiches; french fries, seasoned wedges, onion rings, and breaded poultry snacks; breakfast assortments and side salads; hot and cold non-alcoholic beverages, carbonated soft drinks, coffee, and tea; and traditional Polish homestyle dining dishes historically marketed under its affiliated brand concept, Lesne Runo. The company provides its offerings through quick-service outlets, roadside convenience hubs, shopping mall food courts, standalone restaurants, and franchising arrangements.
In recent developments, Mr Hamburger SA has undergone a comprehensive judicial and financial restructuring process following liquidity challenges that prompted the reorganization and temporary cessation of its traditional company-operated fast-food outlet network. Under executive management appointed in late 2023, the company initiated operational rationalization, contract renegotiations, and structured arrangement proceedings with its creditors. In 2024, creditors formally approved a binding restructuring arrangement that received judicial ratification, establishing structured settlement terms for company liabilities. Following trading halts related to its reorganization status, the company has worked with the Warsaw Stock Exchange to manage its share listings on the NewConnect alternative trading market while pursuing strategic realignments and exploring renewed commercial opportunities for its catering and brand assets.
