Okay. We need to see the rest of the space. Post photos from further back, and photos of the whole room

Pre Reno picture just for gold measure haha

We have a traditional style, with moody saturated colors throughout the house. Updated the cosmetics in kitchen, eventual full hardwoods (this is vinyl for now). The dining room is large and right next to kitchen and we use it so we really don't need any eating space in the kitchen itself.

I'd consider a corner cabinet, in a color that works with one from an adjacent room. You can find them in antique and second hand stores ( I have one that belonged to my husband's grandmother) or lots of options new.

Add some pretty plates on the surrounding walls or maybe a gallery wall including photos of your pets.

Looks like prep and storage would be really beneficial and there are all kinds of kitchen carts at very reasonable prices. Measure the space and suggest getting the largest to fill in the corner, but also be the most useful (black would be complementary). A low unit also won’t overwhelm corner and with art above, it will feel well balanced and inviting.

Suggest adding a vinyl or washable runner by sink to pull everything together.

That wall can be a fabulous storage area. I like the posted option from @barncatz because of the color and the style. Your kitchen is homey and funky and fun. That piece matches the feel.

Or, you can do upper and lower cabinets so you have countertop space for prepping. That would be the most expensive idea.

A moveable cart plus one pantry-like unit would fulfill both needs. But keep the storage part in line with your adorable cabinets. Both sides of the kitchen need to feel the same.

I would remove the over the range microwave, have a simple white hood installed and get a cart or stand for a microwave in the corner. Possibly one that includes a trash bin.
