A food cooking grill with a housing which includes a horizontally disposed grate which is secured to a front frame plate, opposing side walls and rear wall. A front access door is hingedly mounted on the front frame plate. A payment device and a digital display are mounted on the access door and are electrically connected to a control circuit. A solenoid-actuated shut-off valve is interposed in a gas conduit between the burner and a propane or LPG tank coupling in one embodiment of the invention. The shut-off valve is responsive to the control circuit which receives inputs from the payment device and a flame detector and which also controls a flame ignitor and the digital display.
