If you plan to go out to the drinking scene as a way to meet women, you should do further research on the individual cities and see which ones fit your style best.
It would be horrible to get all the way to Ukraine only to learn that the city you chose has nothing to do at night.
It’s most important to know that there is not a “one night stand” culture. Of course there are always exceptions to this, but generally speaking it’s best to keep this in mind.
In modern dating, there seems to be three “usual” acceptable ways of meeting people.
Needless to say, the kind of social environments that locals might use to meet their partners isn’t really available for those of us who travel to Ukraine.
It’s still a society that (thankfully) values longer term relationships with some substance behind them.
Certainly, “casual dating” isn’t out of the question.
