The cost of a meal in the USA will vary depending on where you eat. A meal at a fast food restaurant will be cheaper than a meal at a nice restaurant.
A three-course meal for 2 people at a mid range restaurant is likely to cost you around $60 or £50. This will include an appetizer, main course and dessert. If you're eating at a fast food restaurant, you can get a meal for around $15 or £12.
If you're on a budget, there are plenty of ways to save money on food in the USA. You can cook your own meals, eat out at lunchtime instead of dinner and look for deals and coupons.
With a little careful planning, you can enjoy holidays to America without spending a fortune.
