Very versatile; the Volcano Grill burns wood, charcoal & optionally propane. Plus, in addition to grilling, you can get accessories to make it work as an oven, smoker, fryer and griddle. Or, you can use it as a portable fire pit. Generous venting means high cook temps while the double-wall metal construction means very little heat transfer, making it safe for use on the patio or tabletop.
