You do understand that in communist Russia there were very few restaurants, and only the select few could afford to get in and eat there? Eating out wasn’t a thing at all.

My Russian parents go out for every occasion because they would rather have someone else cook and clean. Plus the food is much more diverse and usually better cooked.

Judging by how now in Russia there are hundreds of thousands of restaurants, I would say that not all Russian parents prefer home cooked meals. But yours do.
