My husband and I are going to Kiev next month ...

Food preferences are quite subjective so I'll give some recommendations for must sees-

Kiev is well known from its architecture. Don't miss the Cathedral of St.Sophia. If you more into parks and wood, the right bank of river Dnipro is covered with green slopes. The Kiev opera house has some good repertoire of Shows and Ballets.  

About the food it is always good to try the local traditional cuisine from what I remember some great dishes are: Borsch , Varenik and Pampushki.

Have a great trip... 

There's a lot to see and do around Kiev. Here’s a few of the most popular attractions:

Andrew's Descent - The city’s most artistic street.
Caves Monastery - Kiev’s premier tourist attraction.
Chernobyl Museum - Grim museum telling the story of the world’s worst nuclear accident.
Independence Square -The focal point of Ukraine’s Orange Revolution.
Khreschatyk -Kiev’s most famous and well-trodden street.
Mariyinsky Park -Charming city centre park. 
Motherland Monument -Giant statue celebrating the Soviet Union's victory over the Nazi Germany.
Museum of Folk Architecture and Life Fascinating open-air museum.
Museum of One Street Small, award-winning museum.
St Andrew’s Church Colourful Baroque church.
St Sophia’s Cathedral- One of Kiev’s most impressive landmarks.

It is said that one can walk from one end of Kiev to the other in the summertime without leaving the shade of its many trees. Most characteristic are the horse-chestnuts (Ukrainian: ???????, kashtany).

Kiev is known as a green city with two botanical gardens and numerous large and small parks. The green nature of the city is probably most notable by the green hills of the right bank along the Dnieper river that have been relatively untouched by development. The World War II Museum is located here, which offers both indoor and outdoor displays of military history and equipment surrounded by verdant hills overlooking the Dnieper river.

Among the numerous islands, Venetsianskyi (or Hidropark) is the most developed. It is accessible by metro or by car, and includes an amusement park, swimming beaches, boat rentals, and night clubs. The Victory Park (Park Peremohy) located near Darnytsia subway station is a popular destination for strollers, joggers, and cyclists.
