As has been mentioned by others, I'll go to McAlister's and promptly stand there looking at the menu board with absolutely no idea what to order. It's not that there isn't anything appetizing, as most of the menu actually sounds decent. Maybe I don't properly see the font or something. It's just that everything blurs together and I am in complete paralysis with no idea what I want to order.
Eventually I'll decide on something and am relatively happy with what I order, and while I'm sitting there chomping away happily, I'll glance up and say "d'oh, should have ordered...". Which I promptly forget the next time.
As to the process? It works well enough. They give you a number, and they bring it out, and like most places, they aren't especially happy about the whole thing, but they aren't upset either. It just is what it is. Better than fast food, not as good as an upscale dinner. Works in a pinch.
