ruby on rails - Using link_to with embedded HTML

I'm using Twitter's Bootstrap stuff and I have the following HTML:

<a class="btn" href="<%= user_path(@user) %>"><i class="icon-ok icon-white"></i> Do it@</a>

What's the best way to do this in Rails? I'd like to use <%= link_to 'Do it', user_path(@user) %> but the <i class="icon-ok icon-white"></i> is throwing me off?

Two ways. Either:

<%= link_to user_path(@user) do %>
  <i class="icon-ok icon-white"></i> Do it@
<% end %>

Or:

<%= link_to '<i class="icon-ok icon-white"></i> Do it@'.html_safe, user_path(@user) %>
