We probably get a "fast-food" dinner once a week (95% of the time it is Chipotle, which is 1/8mi from our house. Dangerously delicious.) and we only go out somewhere nicer maybe once a month.
As for alcohol... I enjoy beer/cider/wine of many varieties. Maybe I'm getting old (33) but bars annoy the shit out of me these days. I was a huge partier in college, but a couple of years ago the following situation happened to me:
We invited probably 10 people to our house for a mini party. Beer, liquor, card games, talking, good times. It gets to be about 11pm and someone says "Hey, lets walk down to the bar thats a mile away!". Sure, why not. We walk down there, and a band is playing (not a really good band), and we sit at a table. We ended up sitting at a table, all trying desperately to talk over the loud band, all drinking the same drinks we were drinking at my house for 5x the cost. I decided at that point that I didn't think bars were worth it to me anymore. lol
