If this is your first time in the city of Kostanay, or even for the first time in the Republic of Kazakhstan, then you definitely need to visit the Coco store first.
As they say, whoever has not been to Coco is a real Cook.
A great store. Always fresh fruits, vegetables and poultry farm products. The prices for eggs are expensive, of course, but not by much. Fruits and vegetables are cheaper than in neighboring stores.
