Reading prices of items on restaurant menus with Meta glasses.

I have been using meta glasses for a variety of things and they have worked well. However, reading menus is interesting. I find that I can ask it to read information on the menu and it will read the items and there prices. Example: Chicken: 4 dollars, Cheese Berger 10 dollars and so on. However, If I ask it to read the price of a specific item say: what's the price of the fruit salad? It will say I can't read prices but am working on doing so or something like that. So, I'm trying to figure out since it can read prices if it reads the whole menu, how can I get it to pick something and read the price of that item? Thanks.
