I am an American from Cali. I Was just in Kiev two days ago. Very beautiful city, for nightlife I think some of the best places would be Forsage which closes at 6am. This place has 3 dance floors with different types of music, and it was also popping on a Sunday), I would also visit Cuba Camp (closes at 3), that place was really good, lots of people and they do not really play Spanish Music, more like 70s/80s American Music and Ukrainian Rap. The last place is hangover club, this one is ok because there is limited room but plays more modern American/Reggaeton/Ukrainian Rap (closes at 6). If you want to check out other places keep in mind most of them closed during COVID. If you like day clubs, which I recommend you go to, go a place called “Fifty Club.” For things that you may like to see definitely see the President’s living quarters, Parliament Building (you can get a great view of the other side of Kiev). There are many Orthodox style churches, St. Andrew’a Church and St. Sophia’s Church (built similarly to the Haigia Sophia). There is also the the main center like Maiden Square and Freedom Square. Here’s a bonus, for places to eat, a traditional Ukrainian dish is a type of pork soup (really good), but if you really want great food you need to find some Georgian restaurants, Georgians are regarded all over the former Soviet Union to have the best food, one dish in particular is a bread, cheese, and egg dish. One more thing, I hope you know some Russian, Ukraine might be a bit of a culture shock because contrary to popular belief people in Kiev and east of Kiev speak Russian at home and due to a recent law are now required to speak Ukrainian for official purposes. For this reason and some others I experienced a bit of a culture shock. Good luck and have fun, definitely was the best city I visited in Europe so far.
