Breakfast - 0-1 time a week I eat out, and this will only be brunch on a weekend. Always eat breakfast at home during the workweek unless I undershopped for groceries on the weekend.

Lunch - 6-7 times out of the week I eat out. Never bring lunch in, and lunch is just an odd meal to eat at home over the weekend.

Dinner - 2-4 times a week I eat out. I try my best to limit eating out during the week unless I am meeting people or have a work event. Most Fridays and Saturdays will be eating out, with Sundays a mix (we like to do a group weekly dinner on Sunday night to enjoy what's left of the weekend).

Living in NYC, I would eat out all the time if food wasn't so expensive!
