How is Google reacting to pages with dynamic content ?

Hi,
Let's say I have a classified website organised like that:
Landing page -> Type of Food -> Restaurants
So that people can click on "Pizza" to be redirected to mysite.com/pizza and see which restaurants are from this category.
One of the restaurants link present on the page is mysite.com/restaurant/casademexico

Now I have a bit of code that will edit the description of the restaurants like that;
"Hey welcome to La Casa de Mexico we're specialised in {{TYPE_OF_FOOD}}"

Using the htmk referer I will change TYPE_OF_FOOD by Pizza since user is redirected from that category.

But La Casa de Mexico will also be listed on the "Tacos" type of food so that if users come from the category Tacos it will read
"Hey welcome to La Casa de Mexico we're specialised in Tacos"

How will google will react to this change of text ? Is there a right way to do it ?

Thank you
