For real barbecue enthusiasts who like cooking outside or organizing a BBQ for larger groups, it's a good idea to buy an outdoor kitchen. These large cooking appliances use gas and offer a broad grill surface and lots of work space. An outdoor kitchen barbecue usually has 2, 3, or 4 burners, as well as a side burner to prepare sauces or side dishes. An outdoor kitchen barbecue often also has side tables and a storage cabinet for the gas bottle and accessories.
