The Google Chrome browser has always leaned towards minimalism and I too did not want to clutter my bookmarks toolbar. Here is a simple solution to a clutter-free bookmarks bar in Google Chrome.
Drag and drop a link to the bookmarks bar and you will notice that it takes up a few pixels of the bookmarks bar with the title text. What I do is have my bookmarks displayed strictly as their favicons, without the title text, because most of the sites that I visit frequently, usually have a distinct icon to represent it.
Try it out by editing a bookmark and removing it's title... and you're done! This increases the amount of visible bookmarks by sacrificing the text.
Easily Access Chrome-specific Pages

Drag any of these links to bookmarks bar:
There are probably more functions you can do with the bookmarks bar than just store bookmarks.
