In many cities in the us eating out is as cheap as cooking. I'm not 100% certain but someone told me it's because you have to consider economies of scale for an eatery and real estate prices and commodity level revenue streams for the supermarket.
Provided the workers scoop deep, a chipotle bowl is generally two meals for me, especially if I get a tortilla on the side to build a burrito with the remnants later. Lunch and dinner for ~$7, breakfast can be a cliff bar for another buck. So ~$56 a week to eat out every day, not too bad if a $50 weekly grocery bill is the rule of thumb.
You barely get two dinners for $50 here in Sweden unless you go for fast food which isn't an option if you're going to be eating out every day. A typical lunch is at least $10.
If I'd eat out every day both lunch and dinner I'm going to pay roughly $800/month compared to my usual $300/month for groceries.
