Having "All Items" as the default of what the customer first sees makes them feel like they have to scroll through all of the items. They do no intuitively realize they can select a category. The Categories should be the firs thing they see, and if the All Items needs to be there it should be at the bottom of the list. You could also make it as one of the things that can be customize in the layout function of the Categories. It really should not be the first thing the customer sees. For us we want our customers to first see the Appetizers.
