Most of my 60s childhood was in a large city, and the rest in a college town. So sure, there was a variety of restaurants. And my parents definitely qualify as the liberal/intellectual elite and are interested in other cultures.
But they were also children of the Depression. Eating at any restaurant was viewed as a luxury. My mom had been trained to work within a food budget, to plan meals, etc. Also my dad was a Methodist minister so when we did go to a restaurant, it would be a “family” restaurant that did not serve any alcohol. (He’s not personally judgmental about alcohol, but some in the church are, so he tends to avoid raising eyebrows.)
In fact, in my childhood the phrase “eating out” meant going to the house of another family in our church, because it was customary to invite the minister’s family to dinner.
Meanwhile, my parents considered me a terribly picky eater because I was reluctant to dig into mystery casseroles containing who knows what. My mom is a good cook and knows tons of recipes, but they are mostly in that same vein which I don’t like. So they assumed I would not like “exotic” foods at ethnic restaurants, and never even tried to take me.
In college I fell in love with Chinese food. It’s SO funny that the OP of the thread that inspired this one thinks Chinese food resembles leftovers/scrapings from plates, since for me its appeal is that it seems just the opposite. To me it’s all that “american” food like meatloaf and casseroles and jello salads that seem like scrapings. because let’s face it, they ARE. That was part of the way my mom learned to stretch her food dollar: make the leftovers into a casserole, etc. I loved going to a Chinese restaurant where things were so fresh, chopped up only hours ago and only lightly stir-fried. You could look at your plate and identify everything in the dish; the vegetables actually look like vegetables and the meat is not overcooked (I don’t do the deep-fried ones like sweet-n-sour pork or general tso’s chicken). The sauce is light compared to heavy cream and cheese sauces used in some food I’d grown up with.
I also eat other ethnic foods now, but can’t claim to be super-adventurous. For example, I dislike feta so when friends are discussing what kind of food we’re in the mood for, I never vote for Greek. So I understand if someone dislkes or is sensitive to ginger or garlic, they will not like Chincese food.
I still don’t like a lot of stiff my folks love. They still think I am picky, and also extravagant with my food dollars. Mom still thinks of me as someone who “can’t cook”.
Anyway, to me this all means you needn’t worry or try too hard to expose your kids to different types of food. After all, it wasn’t at all true that I stayed stuck in the only kinds of food I’d ever known. Just the opposite - I got away from that the first chance I got. You can’t make people like food, and if you try, you will probably make them dislike it, even hate it.
My 7-yr-old actually eats more healthfully at home, but at restaurants feels reluctant to try new things and just wants chicken nuggets and french fries. We aren’t thrilled about that, but are trying not to be too pushy. We are slowly making progress.
