I’m not going to name the restaurant website that I found this on because I like them too much, but:
Since there are only 14 items on the restaurant’s menu, they don’t need a lot of categorisaton. (A split between food and drink might be a good start, though. Just a thought.)
But if you have uncategorised data, don’t offer the useless option to sort by category. Hide it. Otherwise people might write snarky blog posts about you.
