Budget
Midrange
Association Belgo-Congolaise
abc. serves meals for about $10 in a nice outdoor terrace, though sometimes the quality of meals is questionable and the kitchen can close early. the menu includes traditional dishes such as river fish and fried plantains, or international fare like cheeseburgers and spaghetti. food takes a long time to come. you can also espresso coffee rather than nescafe.
The freshwater prawns from the Congo river are incredible - called Cossa Cossa on menus as distinct from imported saltwater prawns which are Gambas - generally served with a garlic and chili pili-pili butter sauce. A plate of these will set you back around $25-$40 dollars depending where you eat.
Top end
The more expensive restaurants are in Gombe.
Papageno at the Memling hotel. Great food. Belgium-French influences with a few Congolese dishes. Rather pricy but worth it, generous portions and great service. Safe parking on hotel premises
Caf-Conc. The most expensive restaurant in the DRC, allegedly!
Ciboulette. Second most expensive.. it's in the Elais compound on your right hand
Chez Nicolas
Le Cercle Gourmand. High class restaurant, belongs to the golf club
Grand Hotel - very ordinary and overpriced hotel food. $25 for very good breakfast buffet. Food and service at the poolside bar have been improved recently and are not too bad.
