Grills Outdoor

Difference between indoor and outdoor grill?
I have a recipe for barbecue and I wonder if it will work better in an outdoor grill?
If "the barbecue recipe" which means a BBQ sauce, no matter – in this case, the flavor of the sauce Marsh conferred by the taste of charcoal BBQ. But if you simply must have that smoky flavor that comes from burning fat and / or charred meat, then an outdoor barbecue can be the way forward.
