A 2-burner grill is enough for grilling. You can get the heat that you need for the food to be cooked properly. However, this will depend on the number of people that you are cooking for. It also depends on the amount of food that you want to cook. A 2 burner with a total cooking area of about 500 square inches will fit about eight chicken pieces, eight burgers, and four steaks. The great thing with fewer burners means that you will be using less fuel to cook.
