How do you put house dishes first in the gallery?

The dish that defines the house opens the gallery, with its photo and its price, for as long as the kitchen can send it. If it sells out, that photo leaves the first slot the same service. Confirm the dish going out today and put its photo first before service. In the sierra the opening photo has been sold out since lunch and the menu still opens on it. That photo holds the first slot while the dish lasts, and it comes down when it runs out.
