Three people suffered severe burns and were airlifted to a hospital after the Molotov cocktail exploded on Sunday night and sent flames through a five-storey building where the restaurant is located in the northern suburb of Aubervilliers, reports the Mirror.
The six police officers suffered minor injuries as they responded and helped the victims.
A freelance journalist said on Twitter that the arson was linked to a "robbery gone wrong".
About 50 firefighters were sent to the scene, French daily Le Parisien reported.
France remains under a state of emergency following a series of terror attacks, but there was no suggestion that Sunday night's fire had links to terrorism.
