Should I create and enter ALL items received from invoice?

I have been entering all restaurant items (milk, meats, lettuce..) in the items account so that my quickbook bill is the exact invoice replica. It has been time consuming and items are always changing. If I enter it into the chart of accounts as combined food only. then how will I know what I my categories are broken down to (Seafood, lobster, shrimp, lamb rack) and also to pull up the prices that we've paid for them? Is there an easier way then to painstakingly entering each item?
