That could be the case. Customers are unpredictable and you will have to work very hard to please them all.
But if all your reviews are negative, it's possible you are doing something wrong. Restaurants are one of those professions where you have to be good at more than one thing; you have to design great menus, you have to buy good food, and you have to hire and manage good staff. As a chef, you may consider your ability to make a great menu the only thing that matters. Unfortunately, your customers disagree, thus causing the restaurant to fail. Sorry, that's life. (Same goes for great doctors that hire incompetent staff. I've had to stop going to a doctor I liked for that reason.)
