Can this Awkward Kitchen Space Become a Pantry?

We have some wasted space in our kitchen. It's a little nook at the back of the room with angled walls and a door that leads nowhere. Inspired by this post on using every inch of a small kitchen, we're thinking of ways it can become a pantry...

Here's a closer look at the space:

The door really is useless (it leads to another nook that leads to a stairwell, which is much more accessible through a different door anyway). And while we haven't investigated all of the rules, regulations, and fire codes, we're pretty sure covering it up with shelving wouldn't be a problem.

The wall is angled, as you can see, so conventional Metro shelving or something similar probably won't fit.

We're thinking of just putting shelves along the right wall and, to add some color and hide potential messiness, covering the front of the area with a curtain.

What do you think? What would you do with this space? Anyone have a similarly awkward kitchen nook that needs to be put to good use?
