I don’t think it’s crazy. It seems very reasonable to me. People eating cake are taking up a table (and probably for much longer than people eating butterscotch budino). And they still need to be served just like people eating butterscotch budino. In my mind, it makes sense for a restaurant to charge about what a dessert off the menu costs.
At any rate, my point is that because the star ratings aren’t all about food, or even mostly about food, they aren’t useful. The write-ups can be useful. The photos are super-useful.
