I think a small, inexpensive change they could do is have "paper" menus that you can get as soon as you walk in so you can read through it while waiting in line.
The menu could explain the process of you will order meat first, then order cold sides, then order hot sides/dessert, then get all your food on a tray, then pay, then you can get beans, pickles, onions, silver ware.
Could even explain how the Bar beverages work. Or how the bar works, i.e. you can't sit down at the bar and order food from there.
having the list of all meats and sides on the menu would definitely help people who are new or the ones who can't decide quickly (aka my wife
) when presented with many options at once.
Mad taco does this. Fuego's does this. Blue Baker Does this. Any place that makes you order at a counter should do this (as opposed to sit down with menus with waitstaff).
