Some takeout restaurants choose to decorate their menus with large, unappetizing photographs of their food. Not a good idea.
I’m no restaurant industry insider but I bet it’s probably better for your restaurant if you don’t show bad pictures of food. Try it with no pictures of food at all and see how it goes.
If you’re a restaurant owner with your heart set on putting pictures of your food on the menu, use good pictures of the food.
Looks great. But don’t use old, faded pictures of the food that have become discolored with time and taken on a disquieting greenish tint that’s only more pronounced under your overhead fluorescent lighting. That just doesn’t help.
Also try this: free self-serve water on the counter. See if your customers don’t enjoy that.
