My wife wants Steak Umms for dinner, but while it's not exactly what she wants, I think she should be happy about getting to eat sushi.
Sushi is great, does she not like sushi?
She hasn't tried it yet.
While it's not her first food of choice and it might be new to her, sushi is a great meal and it can be quite expensive. Hopefully your wife enjoys it and comes to appreciate it.
I really don't appreciate her taste in food as I think she doesn't really know what's good.
Your wife should open her mind a bit when it comes to food and appreciate that there are many great things she can experience. Hopefully you can help her feel more comfortable about trying new foods in the future.
