Font display bad in Safari and dropdown menu issue

Hello,

In the Apple Safari browser the fonts of the template are displayed in bad quality. Especially the headers are bad. Also the dropdown menu from the Topmenu does not expand in width enough; i.e. if you have a long submenu-name, the text of the submenu-name is wider than the width of the background colour of the dropdown menu. Please advice how to fix these problems, thank you.

As for font they are as it. You can replace them with some fonts of greater quality.
For menu we should have an look , send link
