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.
