Wow! I was thinking about this recently. In the past, DH and I have gone out to one of our favorite restaurants for dinner. We have two with sentimental value.
Our first date was at a locally owned seafood/steak restaurant that's been owned by the same family for almost 50 years now. My 1st DH and I had been separated for about 2 1/2 years when DH asked me out on our first date. My son, who was 5 years old, and I lived with my parents. I was teaching school at the time. It was a school night, and I didn't want to be out late, so we chose to do something local. That was November 1, 1990.
The other one is in Monroe (nearest large town, about 50 miles away). There's another locally owned restaurant on the bank of the Ouachita River that's in an old warehouse building from when there was a lot of commerce up and down the river. We ate supper at that restaurant on our wedding night, spent the night in a hotel in Monroe, and left for our honeymoon trip the next morning.
I imagine we'll have take out from the first one. I need to order DH's gift. Other than that, we don't do much. It's almost always a work day for us unless it falls on a weekend.
