I spent about this for a burger at one of those char broiled joints. Tasted like a burger youโ€™d get at a park bbq, overcooked cheap meat. I can make a burger at home 100 times better

But you canโ€™t do it at a park? ๐Ÿคจ

A cast iron flat grill is superior for a good smash burger
Burgers arenโ€™t meant to be crispy the whole way through. ๐Ÿ˜ 
Thatโ€™s why you use medium ground beef, let that fat do the work for you. And you let it rest to retain juiciness. Just lovely.
