It was really helpful. The content was rich and easy to understand, so the explanations were detailed and easy to understand, so it went straight into my head. I was also surprised by the various tips and know-hows that were used in practice. I have nothing more to say except that the lecture was really rich. I learned a lot. Those who are hesitating to take the class, definitely take it. You won't regret it. "This restaurant's lectures are really good. I recognize the restaurant!!"
