A grill having a top wall design incorporating a heat source that efficiently radiates heat towards the cooking cavity but allows the escape of flue gases and hot air towards the rear of the grill to protect the user. The grill has an access to the interior of the cooking cavity. In certain embodiments, a seating mechanism resides in the cooking cavity for accommodating a rack upon which food is placed and enabling the rack to reside on various levels. A rotisserie may be substituted for the rack. A control cavity in another embodiment may be used to house control mechanisms and electrical components sensitive to heat.
