I'm not talking about chi-chi World Cuisine with two lumps and a string of grass on a plate the size of Texas. I'm talking about "ethnic" restaurants that remember what ethnic food means--the food of a people--and incorporate where they are into where they originated.
It tickles me to see a menu in a Chinese restaurant that includes hot dogs (usually only in the children's section). Some people dislike that, saying that it shields kids from having to try new things.
Speaking as a child who wouldn't order anything in a Chinese restaurant except chicken noodle soup, I can tell you that it didn't do my any harm. The chicken noodle soup lured me into going to the Chinese restaurant, where I saw everybody else at the table chowing down on food that looked weird to me (anything but meat and potatoes--and chicken noodle soup--looked weird to me then) but was obviously enjoyable to them. When I got over my pickiness, the first ethnic food I was ready to try was Chinese food. Early exposure turned the trick.
In my short story "Blossom on the Water", Bud Blossom is a Chinese-American who has a houseboat/restaurant in a small Midwestern town. The restaurant is called The Golden Lotus, but it includes catfish sandwiches along with Chinese dishes. His restaurant is always packed, in spite of his personality.
If I may segue into some blatant self-promotion, I've collected the stories I wrote about Bud and some of his customers/employees into an e-book called THE KING OF CHEROKEE CREEK. It's available on Amazon for Kindle (text-to-speech enabled) and on Smashwords in various formats, including ones that make it readable on or printable from a just plain computer.
