Pictures of the space will help with ideas. (If you attached a pic, it didn't come through. Try in a comment - the site can be glitchy.) Would the cabinets be deep enough for cookbooks? Pull-out trays can make deep areas more functional.

I guess you could put a lazy susan in there. It depends on how big your kitchen is, and what other items you have to store.

If it doesn't have a lazy susan, you can probably order one to fit if the shelves are removable. Otherwise, you can buy lazy susan trays to set on top of the shelves. Copco makes 18" trays with non-skid rubber.

I put glass doors on them in my last kitchen and displayed pretty stuff

I put the fancy dinnerware that we literally never used. Then, when I remodeled, I swapped that out for a corner cabinet with no doors. Now it holds our every day dishes and glasses. The fancy dinnerware was relegated to the basement in china storage boxes (why I spent $$$ to store plates I haven't used in 10 years is beyond me, but we do strange things when packing up a kitchen).

I use a pull-out basket to access any items in the center of them. Just a long plastic storage bin with a handle grasp. Mainly light packages in them - baking do-dads or tea varieties.

Once you pull out a basket. You have visual access to both sides. I stored one or two varieties of bulk purchases on each side (I buy by the case when items are on sale...)

My last corner cabinet had spaghetti sauce on the right, and pasta boxes on the left on one shelf, home canned chili on another shelf pared with home canned beans on the other side. On the top shelf I stored my extra ziplocks and foil or plastic wraps that did not fit in drawer.

I buy a year supply of items in bulk when really good sales hit.

I ripped the door out, added molding to the opening and painted the whole inside black. I have deep narrow baskets on the shelves which are easy to pull out (on felt so they don't scratch the paint). I keep our medicine, band-aids etc in the baskets. Has worked for us for 10+ years.

I actually keep most of my everyday dishes in mine and it has a leaded glass door - I have an older kitchen. The harder to reach corners have matching serving dishes or glasses that I don't use much.

This is what I have in mine. It's not super efficient, but I didn't want to crowd things in. Behind the glass measuring cups I have nuts, dried cherries, and raisins for salads and oatmeal, and the very top shelf, which I need a stool for, has rarely used things.

I know others aren't a fan of those type of cabinets, but I do like mine. I had lazy susans made for all but the bottom shelf. I can reach to the back of that one. I bought the hardware for the LS at Menards and had a guy cut them from good quality plywood. I sanded the edges and my husband installed them. Love them!
