Giving administration access on an information only ("static") site?

I'm developing a site for a local restaurant. I'm using drupal because they wanted to easily modify things like daily specials and menus. I'm currently going through the process of reworking the bluemarine theme to fit my design. They have no interest in having user logins for people who are really just going there to check out the menu and the phone number.

My problem then was how to give easy access to the administration pages. My solution was to put a small icon on the bottom of each page. This seems to work fine except in the task of content creation. After save you remain on the "site" side of things, as opposed to the "administration" side. Granted it's not really an issue because they won't be creating pages or stories, just modifying existing ones.

I'm just curious if other's run into this dilemma of not wanting user logins and how did you solve it?
