You're right, in the days of socialism, people had little choice of products. Especially there were few street vendors of food, and those who did monotonous dishes. At least it was here.
Now we have a wide variety of delicious dishes. Modern people can buy themselves a variety of ingredients and make delicious dishes. There is also an opportunity to go to a restaurant or a cafe and buy yourself a delicious dish. There are some themed cafes that make dishes of foreign cuisines. I know restaurants that make only Chinese dishes or Italian. But this is only in large cities.

I love variety in food. That is, it happens that we prepare dishes of national cuisine, and sometimes there is a time when you just want to eat pizza. I also like to visit various festivals, and there are usually a lot of sellers going. You can often try various delicious dishes that people have come up with themselves. It is interesting.
Choose your own food, this is not one of the many freedoms that we have :)
Thank you
