He'd run it with kindness and integrity. He would hire people based on their skills and not discriminate. For example, he might hire a werewolf as a chef if they're good at cooking.
Harry would likely use his knowledge of magic to make the restaurant run smoothly. He could use spells for cleaning, food preparation, and customer service. He might also use his connections in the wizarding world to source the best ingredients.
Harry would probably make the restaurant a place that promotes unity. He'd welcome all kinds of customers, whether they are pure - bloods, half - bloods or muggles. He would create a menu that caters to different tastes. And he would use his Gryffindor courage to face any challenges in running the business, like dealing with difficult customers or competition from other magical restaurants.
Maybe for love. They might have fallen deeply in love and want to be away from the prying eyes of the wizarding world.
In such a fanfiction, the restaurant might be filled with magical elements. For example, the dishes could be magically prepared and have unique effects. Maybe the waiters are house - elves who are now free but choose to work there. The interior could be decorated with Hogwarts - like features, like floating candles and portraits that talk.
Mostly wizards and witches, of course. They would be the main clientele as they are the ones who can fully appreciate the magical elements of the restaurant. Students from Hogwarts during Hogsmeade weekends or holidays would also flock there.
Snape would likely be angry at first. Harry has always been a source of trouble in his eyes, and running away would just add to that perception. He might mutter some sarcastic remarks under his breath about Potter's irresponsibility.
In such a fanfiction, Harry Potter might be seriously injured or even die. This would completely change the course of the wizarding world. His friends would be devastated. Hermione might try to use all her knowledge to find a way to reverse the situation if possible, while Ron would be furious and determined to find out who was responsible.
He could be shocked. Maybe there are some fanfictions that take a very dark turn or have unexpected pairings that he never thought of. He'd probably need some time to process such strange ideas. And he might also be curious to see how far the creativity of the fans can go. He might even get some new ideas about his own life from reading some of the more imaginative fanfictions.
It could be a wizard - themed restaurant. There would be magical dishes like butterbeer - flavored ice cream, and the tables could levitate a bit to give a floating effect. The staff might use magic to serve the food, making it a truly unique dining experience.
He might feel a bit embarrassed. After all, these are often people's wild imaginings about his personal life.
The fandom would be divided. Some fans who are deeply into fanfiction would be disappointed and might feel like a part of their connection to the 'Harry Potter' world has been cut off. However, others who are more focused on the official works might not be as affected. There would likely be a decrease in the variety of fan - created stories, which could limit the creative exploration within the fandom.
The characters would change a great deal. Harry, for example, might be less of the pure - hearted hero. He could have a more cynical view of the world around him, similar to Brightburn. Hermione might be more distrustful of Harry's new - found darker tendencies. Ron could be more afraid of Harry and his powers, which would strain their friendship.
