I need help with the ye concert

My friend and I are traveling to Romania and Italy in July. We’ll be in Constanța from July 6 to July 15, and we’re going to the Beach, Please! festival from July 8 to July 12. Then we’re flying to Rome from July 15 to July 19 for the Travis Scott concert on July 17 and the Kanye concert on July 18 before flying home.

How much money do you think I should budget for food for the entire trip?
