this is not a bug but a theme issue, so i've moved your post to the Themes Support forum.
You'll have to change the width of the menu item columns and its easy thanks to Twitter Bootstrap.
Open main/views/themes/tastyigniter-orange/partials/menu_list.php on line 32 and 38.
Since you are not displaying menu item images, change col-xs-9 to col-xs-7 on line 32 and col-xs-3 to col-xs-5 on line 38
It should look like after changes
<div class="menu-content <?php echo ($show_menu_images === '1') ? 'col-xs-6 col-sm-7' : 'col-xs-7'; ?>">
<div class="menu-right col-xs-5 wrap-none wrap-right">
