Should I use HTML/CSS or WordPress for my first restaurant website project?

I'm planning to build a simple website for a small restaurant, which will include basic sections like Home, Menu, Location, and About Us. I initially thought it would be an easy project using just HTML and CSS, since I'm a beginner. However, I've heard mixed opinions about whether using a CMS like WordPress would be better for easier updates. I'm looking for some advice on whether to stick with the basics or go for a CMS. What do you think?
