When CJ’s Restaurant opened in Nairobi in 2018, it quickly became a game-changer in Kenya’s food industry. Known for its high-quality meals, generous portions, and inviting ambiance, CJ’s Restaurant Chain has become a favorite dining spot for professionals, families, and food lovers.
But behind this success is Ahmed Omar Mandela, a Ugandan entrepreneur who transitioned from banking to building a multimillion-dollar business empire. His journey—from managing a small hardware store to launching one of East Africa’s most popular restaurant chains—is a story of vision, resilience, and innovation.
From Banking to Business
Born in Kampala, Uganda, in 1958, Ahmed Omar Mandela (also known as Hajji Omar Mandela) studied Economics at Makerere University before starting his career as a banker. However, his entrepreneurial spirit soon led him away from the corporate world.
In 1983, he founded the Mandela Group of Companies, beginning with a hardware store. Over time, he expanded into tyre trading, automobile spare parts, and fuel stations—laying the foundation for what would become a vast business empire.
The Birth of Café Javas (CJ’s Restaurant Chain)
While running City Oil, his fuel station business, Mandela noticed an opportunity: customers needed quality food options while refueling. This insight led to the launch of Café Javas (CJ) in Uganda—a restaurant strategically placed next to his petrol stations to serve motorists, corporate workers, and middle-class diners.
The concept was a hit. With nine branches (eight in Kampala and one in Entebbe), Café Javas became Uganda’s go-to restaurant, famous for its delicious food, large portions, and excellent service.
Expanding to Kenya: Challenges and Triumphs
Buoyed by success in Uganda, Mandela set his sights on Kenya. However, his entry faced a major hurdle when Java House, a leading Kenyan restaurant chain, filed a trademark lawsuit against Café Javas, claiming the name was too similar.
After a legal battle, Mandela rebranded to CJ’s Restaurant, officially launching in Nairobi’s Koinange Street in April 2018. The restaurant’s modern, affordable, and high-quality dining experience quickly won over Kenyans.

Since its debut, CJ’s Restaurant Chain has expanded to five locations in Kenya, including:

With a menu boasting over 300 dishes, CJ’s offers everything from breakfast favorites to gourmet burgers, pizzas, and desserts, catering to diverse tastes.
Beyond Restaurants: The Mandela Business Empire
Ahmed Omar Mandela’s success isn’t limited to hospitality. His Mandela Group of Companies spans multiple industries, including:
- Mandela Millers – Supplies wheat and maize products for his restaurants.
- City Tyres – Uganda’s largest tyre manufacturer.
- City Oil – A leading fuel and lubricants company with eight stations in Kampala.
- Mandela Auto Spares – A top distributor of automobile parts.
- City World – A major FMCG distributor for global brands.
With over 5,000 employees, Mandela’s businesses are among Uganda’s largest private-sector employers, contributing significantly to East Africa’s economy.

A Leader in Sports and Community
Beyond business, Mandela is a respected sports figure. In November 2021, he was elected President of Sports Club Villa (SC Villa), one of Uganda’s most successful football clubs, showcasing his commitment to community development.
