How much should a household of two spend on groceries?

I would say about 100-150 dollars. That's how much i useally spend on my groceries a month. I spend $1300 to $1500 for a family of 4 (kids 6 and 10 yrs) plus about $300 in restaurants.

Well if you are in Australia the average money on groceries is usually 300 dollars, i think it is a bit expensive but that's my best answer.

This varies widely based on the area, type of restaurant, and time of day. Lunch menus tend to be cheaper, as do local joints compared with national chains. But for dinner at Applebees, I'd say 30-40...

the amount that comes from your face

It depends on if it is a purebred or not, those are more expensive than mixed breeds.
