Diva is tucked away in the laneway Донец-Захаржевсково 5, between Sumskaya and Pushkinskaya streets; only 5 minutes from the History Museum Metro.
The restaurant is BYO, which is great in Kharkiv. You can buy beer or other drinks, but are welcome to bring in bottles of wine or something stronger if you so wish.
The menu is traditional Russian, of good quality and the service is the fastest I have experienced in the city with prices very cheap.
The only negatives for this restaurant is a “traditional” stand up toilet and the “Euro-disco” music. Besides that, good place if you want a good group meal.
