Some foods are just better suited for restaurant cooking because they have better equipment, especially wrt thermal output. It's almost impossible to make great pizza at home because pizza ovens get twice as hot as the average home oven, Chinese restaurant wok stoves have way higher flames than a home gas stove, etc.
Likewise it's absolutely retarded to deep fry anything at home because the cost of oil alone makes it more expensive than buying slop out. Not to mention the disposal, cleaning, fire risk and smell getting into everything. Ugh
