As much as I love grill food.
It is my favorite...
A grill is mostly a grill isn't it? I've NEVER had bad grill food (that wasn't caused by the chef anyway)
Be it from park charcol grils, those little hibatchi grills, built in home grills or fancy grills.
As long as it's a real grill it's going to be delicious.
So it's really just a matter of getting the amenitites you care about when cooking.
