Food is a separate conversation. I do not recommend ordering immediately for the entire period of rest (90 hryvnia per person), as the quality leaves much to be desired, and money for food is not returned. There is a lot of food, but all peppered, from canned food and from Maggi cubes. Cutlets must be burnt on one side. Children refuse to eat. In addition, the meal schedule is inconvenient 9.00-13.00-19.00. I advise you to look for food in other canteens, for example, on Rocket or Mechta. Judging by the menu, food there costs 70 hryvnia, it's worth a try. Or you can eat in a cafe, since there are a lot of them.
When ordering in advance, do not believe that the places will be only a week later. This year there are few vacationers in Koblevo and full of free places at all bases. Good luck!
