Well, for my family of 3 (DH and I have a 7 yo DS), we spend about $27 per counter service meal, and about $60 for sit downs. Most meals for DS are in the $5 - $7 dollar range.
I budget $150 per day for everything (food, drinks, souvenirs) and I rarely spend that amount. I usually come home from vacation with enough for my deposit on the next vacation.
