The practically flat portable cookers are ideal when it comes for saving space. Storage becomes a cinch with its flat pack design. A step up from that would be slide-out grills like the Gunni Movable Kitchen. Sleek in esthetic, the appliance has drawers containing the grill, cutting boards, cutlery and other Father’s Day BBQ essentials. Or for the more tech-savvy dads, there is the voice command barbecue from Lynx. It has a Siri-like feature to make sure any mid-grill queries are taken care of.
