Most places displayed the food offered in representative models. The food that was delivered always matched the model as if they had a copy in the kitchen and worked hard to match it. These models also made it easy for those of us who don't read Japanese (Kanji in particular) to choose our meals.

Note the prices on these huge plates of Sushi. Gorge yourself or share between two people for about $20. (Not all food was this inexpensive.)
