Since you just came back from a date, could you describe a date from two UJ characters who are canonically dating?
Odnduudbr okay so these are more like loose ideas strung together but!!!
Undyne and Alphys have awful ideas for dates. Alphys thinks eating ice cream and watching anime is a date which is okay once or twice but girl expand your horizons and Undyne wants to do physical activities like go fencing or watch a wrestling match or something.
If they ever go to a dinner date it would be great for only them. Alphys' order would be wrong and Undyne would be the "She asked for no pickles" but she also would absolutely go into the kitchen and "teach" the chefs how to make food if she declares the restaurant's food is not good. It would start a fire of course and they would be kicked out but hey, that's romance for ya.
