What foods at restaurants are you always or almost always disappointed with.
I have 2,well 2 to start with. Nachos and chicken fried steak. Too many places use nacho cheese instead of melting grated cheese and they'll try and put refried beans on their nachos to make it look as if they are "loaded". Fresh jalapeños also are 100x better than pickled.
Also frozen chicken fried steak sucks. Freshly breaded is the only way to go. Most frozen CFS also have more breading than meat. It makes for a terrible meal
