Hi there, looking in the source code for the page the line divider is set to 50% – so technically it is in the middle. You can adjust it further to the left using the css below (copy/paste into your style.css file and save).

.menucard-devider {
left: 44%;
}

Have you made any other css adjustments which could have moved the menucard content over?

To divide the pizza section you’ll need to save it as a separate category, maybe spilt the pizza’s by topping into smaller categories?

The second page is centered, but you have it set to sidebar right (with nothing in the sidebar). So you’ll need to go into edit that page, and from the page settings turn off the sidebar and set it to a fullwidth page. Screencast – http://screencast.com/t/gyUSqRJpg
