>>21462450 (OP)Peking duck. There is some tricks they do that makes it fucking amazing, and it's a right pain to replicate at home.
Any ramen/pho type soup where you have to make stock for hours on end and the whole process is like 2-3 days is just so much easier to let a restaurant do.
Same for dry aged steak. That shit requires specialized equipment, a month of time, and it's just not worth it. So much easier to get it at a restaurant.
Pizza is also a right pain in the ass because it requires special equipment and takes 2-3 days proper.
