This DIY is so simple - we used a Large Point White Sharpie Paint Pen (Water Based), and went to town (as they say). We have even added a few more for fun.
The best part is the cost -- almost nothing. The fun factor. --- And -- that's a big And -- we get to give the windows a good clean when it is all over (that's always a win).
For food here at the Cafe -- we are going Sandos all the way. Split a Club Sandwich. They are huge and you and your Valentine will still have room for dessert.
