Did I say briquettes? They’re barely better the gas grilling (At least you aren’t steaming your food like on a gas grill).
I said charcoal. Any hard wood will do. Mesqeete from Mexico is reasonably priced.
My parents own a big fancy gas grill. The last time they were over I threw some hot dogs and burgers onto my Weber kettle grill with good old fashioned lump charcoal. My dad spent the whole time talking about how he needed to get one of those himself.
