It really depends on how busy we are on the weekend, and how busy the workweek is. I usually try to make two "big" meals on Sundays so we can have leftovers for dinner most of the week. During the academic year DH NEVER gets home before 7-7:30, and during spring semester we both taught until 9pm on Tuesdays and Thursdays. It's just too late to cook dinner at that point- it's practically too late to EAT dinner at that point- so we'd often grab a small pizza to split or maybe a sub.
If we are both having a busy work week (when we aren't teaching stupid hours), it really depends on how tired we are. If we stop for a beer after work (3 microbreweries within a 5 min walk of our house), chances are good that we'll get take out, as we can bring it into the taprooms and have dinner with our beer. Local take out choices are Thai, pizza/subs, Mexican, or a really good sandwich shop. They all are sit-down too (and the owner at the Thai restaurant is a master mixologist...) but we do take out. There is one nice sit-down restaurant in town, but it's small, busy, and expensive; we go there maybe 2 or 3 times a year. There is also a British-style pub that we've been to a couple of times, but I don't love their beer selections and their food prices are a little high.
On a "good" week, we might do take out (to the taproom) once a week. On a crazy week, maybe 3-4 times. We rarely go into the "big city' (that'd be Bangor, ME). There are some terrific, upscale places there- pricy, but the food is amazing- but it means driving home, which means someone has to not drink. Although you can't tell by my post, hahaha, we are NOT alcoholics, but we enjoy a beer/wine or two with a nice meal... but won't take the chance on driving home. We stay right in our neighborhood, walk into town, and can eat and drink whatever we want (and the bartenders all know that we are pedestrians!)
