Should you use one type system for dish names and descriptions?
Yes, one type: the dish in one size and the description in a smaller one, the price in the dish size. Do not add a third decorative face for the names if the description is already hard to read.
Write to us. A quote with no commitment.

Bring the current menu and mark which lines are names and which are explanations. There is one face for the dish, another for the wine and another for the price, and none of it looks like the sign. You get the menu in two sizes of the same type and the file with that type embedded.
