Can I include restaurant experience on my resume as an English teacher in Korea?

Hello! I am preparing to work as an English teacher in Korea. Recently, I've been thinking about my resume. Since graduating from university last summer, I've had difficulty finding a job, and I'm unsure how to handle my short work experience before starting my English teaching career. A few months ago, I started working part-time at a restaurant to save money for my move to Korea, and I'm wondering if I should include this experience on my resume. I believe the various experiences and skills I've gained from working at the restaurant could be beneficial for English teaching. The career advisor at my TEFL school also advised me to include this experience, but I would like to hear other opinions. Do you think hiring managers in Korea would view my first job after graduation, which is in a restaurant, negatively? Or am I worrying too much? I would appreciate your advice.
