Welcome to the Q&A Forum

Hello ReniaEats, Googlebot and Google's algorithms are much more sophisticated than those at Moz. If you are sure that the keywords are only used a couple of times on the page, with the exception of templated items like those in the menu, I wouldn't worry too much about it. Just write in a language that you think will be compelling to visitors and don't be too concerned with adjusting keyword density on the page. With that said, you may also want to look at the code just to make sure there is no hidden text. Just do a CTL+F (Find) search when viewing the source code and type your keywords to see where they show up outside of the navigation/menu. If you wanted to share the site I'm sure someone could have a look and let you know if there is anything to be concerned about.
