I prefer the other end of the curve (if that makes sense) where something is time consuming and hard to make at home YET you can get it incredibly cheap comparatively and in good quality in a restuarant. Ramen is the prime example of that.
It is compared to the cost of making an authentic ramen broth at home at the scale of feeding 2-4 people. Pho has a similar property. I've made homemade pho broth once and it was very hard work, fairly costly, and it resulted in something that was pretty good, but not comparable in quality or price to something I could have bought in a restaurant down the street. (admittedly typically also cheaper that ramen)
