Korean barbecue is quite healthy as long as you don't use processed or over-sweetened sauces for the marinade and balance meat with vegetables. Since the barbecue grill will have a drip tray to catch excess grease, you don't have to worry about eating too much fat. You should place your grill where there's plenty of ventilation and make sure that it doesn't produce too much smoke. One way to reduce smoke is to pour a little water into the drip pan to neutralize the grease that drains off.
