I try not to eat fast food, unless I'm in a hurry. I'd say $8-12 on fast food, depending on the restaurant.

If it's a sit down place, it really depends on what I'm in the mood for, and the prices.

Could be anywhere from $12-$100+. It also depends on if I buy alcohol beverages too.

I try not to spend more than around $40 a day on food, including breakfast, lunch, and dinner, but It's definitely hard sometimes.
