Dude, Omaha has like 10 restaurants on each block - and they're mostly awful. I never know if it's the local tastes or that they just eat what they can get.
White people aren't raised to like spices. No Mom, salt and pepper aren't spice. You have to understand that most of us came from Irish, English, and German immigrant families. Those aren't cultures exactly known for interesting, flavorful dishes. So we ate what our Mom's cooked us, which is what their mom's cooked, and so on. Spices, let alone *spicy* foods are not common. Most peoples pallets were never introduced to it, and it's only as some of us Gen X'ers and younger start to get out and about a bit more that we realize there is more to food than crock pot meat, potatoes, steamed carrots, and gravy "spiced up" with salt, a dash of black pepper and ketchup.
