Menu design is a great candidate for psychology experiments. It's easy to do A/B testing by giving different menus to different tables at the same time. The end goal is money spent or items sold, which is a simple number you'll always know exactly. However, you have to be careful to not overreach in inferring why people do things: >“The dollar sign is a pain point that reminds the diner that they are spending money,” says Allen. “By just using the figure, or even better, writing it out in words, it can reduce that pain.” This sounds like a rationalization. It could be true. But if I were a menu designer, I wouldn't try to use it to predict anything beyond including currency symbols.
