I've been using Angular with Grails for the last 6 months (but these comments would apply to Rails or any other server-side MVC framework) Although we do use Grails MVC to build the Angular-powered HTML pages, the pages are very nearly static HTML. We're using Grails to create a JSON API that the Angular controllers and services communicate with. We are also using the Grails resource pipeline (similar to the Rails Asset Pipeline) for LESS to CSS conversion, .js and .css catenation and minification, etc. If you're creating "rich" front-end apps (as we are) you will be using your server-side framework mostly for implementing REST services with JSON (or XML, etc) However, you could also use Angular to add new functionality to some existing pages in an existing app.
