My partner and i often go on "dinner dates," and for special occasion we'll go out to a really nice place (like birthdays). As far as a special planned date, it takes more time and effort to do, than just being like "lets have a nice dinner," but we are going to Disney this weekend and i kind of count that as a date.
We used to go out a lot, but I wouldn't really say we went on dates all that often. Since we had our daughter though, we've tried to make a special night just for us once a month minimum...dinner at an adult establishment maybe, or out to a movie...a planned and deliberate night for just us two since we can no longer just up and say "Hey wanna grab a beer and some wings?" and walk out the door! We appreciate the times we do get out together alone a lot more now!
