As I said in my other comment, my total cost per meal per person with hello fresh is £5. You literally can't eat that cheaply at a restaurant. Even if you have the cheapest item on the menu and only ask for tap water to drink, it will be more than £5/person, and then you have to include the cost of getting to the restaurant and back. I was going to say that maybe you could eat for less if you were happy with a frozen burger or hot dog, but even cheap pub food will cost you more than £5 per person.
