If people realized just how badly they're being [censored] by most restaurants, they would get up and walk out, never to return.
The big-picture problem is that average Americans have become so disconnected from food that they have no idea if they are being ripped off or not. They don't know what raw ingredients cost. They don't know what's in season. They don't even know what's grown in their region. So they're incapable of making informed choices in restaurants. Hence, the $30 tater tots I've been mocking for the past few months.
And it's not just Hawaii. It's nationwide. The sad part is that there are small places which are "bringing it" from a culinary standpoint. But they're languishing because diners choose TGIMcFunsters*, where most food is dumped out of a bag into a deep fryer. The perceived "deal" of fried agricorp food has squeezed out the places that are actually trying to cook. Since our populous has become hopelessly ignorant about food, they're easy prey.
And even in fine-dining, where there is less shenanigans, there are still shenanigans -- such as "truffle" oil.
