There is a regular grill on the side patio and a flat top grill on the upper deck. These are both gas grills and the gas bottles have gas level indicators on the line by the knob. There is an extra bottle located behind the gate on the side patio if any of the bottles run out. If for some reason you run out of gas completely let us know and we will get you a bottle as soon as possible. When you are finished with the grills please make sure the gas bottle is turned off and the grill is scraped down and clean. This will help with any unwanted visitors.
