php - Only show line of code on a specific page -

-

I have a group of different menu pages (using custom fields) for a local restaurant and only one PDF menu One of these pages I want to show is trying to add a line of code in the templates for menu pages which only appears on the page with 'Slug' wine-list.

Here's what I have done, but it does not work: 

  & lt ?? Php if (is_single ('wine-list')) {echo & lt; A href = "LINK-TO-PDF.pdf" target = "_ blank" & gt; See our complete wine list & lt; / A & gt; '; } And {}? & Gt;

If 

  & lt; Use php if (is_page ('wine-list')) {echo & lt; A href = "LINK-TO-PDF.pdf" target = "_ blank" & gt; See our full wine list & lt; / A & gt; '; } And {}? & Gt;
