Not sure how well the site's font renders on other machines/browsers, but on Windows 7 Pro x64, Google Chrome 26.0.1410.64 m, your font renders with holes in it. Very odd.
Chrome's web font rendering on Windows is terrible (as is its high-DPI support and text color accuracy). It does this to virtually every custom font without super thick weight. I've opened bug reports since early 2012 that keep getting pushed back to the next milestone indefinitely. There's not much that can be done about it except use default fonts or accept that things will look kinda crappy on the largest browser/OS combination.
