couples eating?

Based on my experience, it is more economical to buy groceries and cook every meal, that is, if you are a good cook and don't mind eating the same menu for two meal times. But if you like to eat different food for breakfast, lunch, or dinner, or if you want something new each meal, I think it is better for you to eat outside. Anyway, there are restaurants out there which are affordable.

i think its not possible to eat out every other day, still more important is what you are eating, you will be eating much more nutritious diet at home in comparison to if you are eating outside,

I think unless you're eating off the .99 cent menu every day at McDonalds and you only order 2$ worth of stuff per meal it's definitely cheaper to buy groceries and cook. For one $6 value meal I can buy enough food to make three meals for myself. Cheap one's but still, it'd be cheaper.
